BEFORE YOU START — THE SYSTEM IS THE PROCESSGerma-Tech abrasives and ancillary products are graded and tested for compatibility with this product and the process on this sheet — that control is what makes any problem on the job assessable and fixable. Once a non-Germa-Tech product has been used at any step, what actually touched the panel can no longer be verified, and issues that arise cannot be fairly assessed — by us or by anyone. Use the system through the whole process, and if something on this sheet does not fit the job, talk to us before you spray. Refer to the GERMA-TECH APPLICATION STANDARD.

05DRYING & CURING

THE SNAP PRINCIPLE — ENGINEERED FOR ONE-HOUR TURNAROUNDOnce baked and brought back to temperature, the cooling of the coating “snaps” the outer layer — a deliberately engineered harder top surface. That snap is what lets this clear be de-nibbed and polished within ONE HOUR of cooling, where a conventional clear needs overnight. Jobs are polished and out of the workshop faster — a unique engineered design, built for high-volume shops. ▶ Watch the snap in practice.

BAKE TEMPERATURE IS METAL TEMPERATUREBake time starts when the panel reaches temperature, not when the door shuts. A cold panel in a 60 °C booth takes roughly ten minutes to get there — add that to the schedule or the film is under-cured. Ensure bake times commence from when the oven reaches temperature of 60 °C and not before. Dry times are greatly impacted by the thickness of the coating and the ambient air temperature when applying. When temperatures are below 23 °C adjust drying times or increase baking times accordingly.

Read it like the panel: substrate at the bottom, clear on top. Faded rows are the rest of the system at its normal build. See the Coating Thickness Guide.

MAXIMUM 60 µm of this product — THE RED LINE ON THIS PRODUCT'S ROWPast that the film cannot get its solvent out: solvent pop, die-back, a soft film that never fully hardens, and cracking later. Modern polyurethane is a low-build system: less is better. Three thin coats do not fix what two correct coats did — they add microns and take the film past the limit. The red line on the FULL BUILD row is the 300 µm whole-panel ceiling — every layer added together.

07RECOAT & REWORK

Recoat — this product over itselfRECOAT WINDOW — 15 minutes at 20 °C panel temperature from application, IF THE JOB IS NOT BAKED. Baking closes the window: after any bake cycle there is NO recoat window — abrade before recoating (see below). Flash-off is the MINIMUM time between coats; the 15-minute window is the MAXIMUM, and it moves with panel temperature — hotter closes sooner.
Over the previous coatBasecoat → clear: allow 10-15 minutes air-dry, then spray clear at once — within 1 HOUR at 20 °C of applying the basecoat, all colours alike. Past 1 hour, scuff and re-apply basecoat before clearing. Cure-limited — heat shortens the window. Waterborne basecoat → clear: apply clear after the film turns matt; must force dry the basecoat before clearing (60 °C, 5-10 min). Timing is humidity-driven, not temperature-driven — a maximum window is still to be ruled. 2K colour → clear: sand first, ALWAYS — lightly sand the colour before applying clear regardless of elapsed time, and do not sand and recoat finished surfaces without baking.
Polishing / de-nibbingAllow 15 minutes self cooling after bake then wet 2000 grit & polish
HOW EACH COAT BONDS — WHY EVERY WINDOW ON THIS SHEET CLOSESThe whole repair is designed as one system applied within one overall time frame: the primer is dried and sanded, but from colour onward it is a concurrent, same-day process — and every window on this sheet exists to keep you inside it. Within its window the next coat fuses chemically with the film beneath; past it, the film has cured and adhesion must be made mechanically — abrade, degrease, recoat. Heat closes windows sooner: cure runs on temperature, not the clock. Straying from the timed system — jobs interrupted, held over, stretched — is where the problems start. Full explanation in the GERMA-TECH APPLICATION STANDARD. If in doubt, abrade.
IF YOU MISS THE RECOAT WINDOWOnce the film has cured past its recoat window, do not put another coat straight over it — the new coat sits on the surface and lets go at the interface. Abrade the whole area first (P800 wet or a grey abrasive pad), degrease, tack off, then recoat.
SANDING A CLEAR THAT IS STILL CURINGA 2K polyurethane clear is polishable in a day but takes up to 12 weeks to reach full cure — under the skin the film stays soft for weeks. When de-nibbing or flatting, work with care: a soft film cuts faster than a cured one, and it is easy to break through the clear into the basecoat, which turns a nib into a repaint. After any sanding, give the panel a light bake before recoating or polishing — sanding opens the surface of a part-cured film, and coating over it unbaked is the classic recipe for a fry-up: solvent attack lifting the soft layer beneath. Do not sand and recoat finished surfaces without baking.

08DENIB & POLISH GUIDE — STEPS, GRITS & ABRASIVES

StepGritWhat you are doingGerma-Tech abrasives — examples by part number
1 · Cure firstPolishable in a day, fully cured in up to 12 weeks — the film under the skin is still soft. SNAP CLEAR is the exception to overnight: bake, then let the panel COOL — the snap of the outer layer on cooling gives a harder top surface, and de-nib and polish can start within ONE HOUR of cooling (see THE SNAP PRINCIPLE above). After any heavier sanding, a light re-bake before polish still applies.
2 · DenibP1500 spotIsolate the nib and work the nib only — not the panel around it.TUNGSTEN DENIB BLOCK (PB041) · ORBIT 75 mm P1500 spot disc (GN751500)
3 · RefineP1500 → P2000Take the denib scratch out and flat any texture. Wet by hand or dry on fine film discs. Never jump a stage.GTEC wet & dry 1500 (A208-10) · 2000 (A209-10) · ORBIT film 150 mm P1500 (MF6-P1500-100N) · P2000 (MF6-P2000-100N)
4 · Finish sand3000 → 5000Napping discs take the P2000 scratch to polish-ready — this stage halves compounding time and is what kills swirl on dark colours.NAPPING 75 mm 3000 (A408DM1-3000) · 5000 (A408DM1-5000) · 150 mm 3000 (A408DM2-3000) · 5000 (A408DM2-5000)
5 · Compoundcutting compoundCutting compound on a cutting pad. Low speed, light pressure, keep the head moving — heat is the enemy of a young film.Cutting pads: 6" (A903-2) · 3" (A904-2) · 75 mm yellow (A905-1)
6 · Polishfinishing polishFinishing polish on a soft foam pad, then a clean microfibre. Edges and swages by hand.Foam pads: 6" (A903) · green soft (A905-3) · black final (A905-4 / A906-4)
WHY 3000 AND 5000 EXISTCompound is an abrasive too — it just has no number on the box. Going from P2000 straight to compound forces the compound to do sanding work: more heat, more time on the panel, and the fine scratch that comes back as swirl once the film hardens. The 3000/5000 napping stage finishes the sanding with GRADED abrasive, so the compound only has to gloss. On blacks and dark colours it is the difference between polished and hologrammed.
DO NOT BREAK THROUGHA soft film cuts faster than a cured one. De-nib with the smallest tool that does the job, check your progress constantly, and stay off edges and swage lines — breaking through the clear into the basecoat turns a nib into a repaint.
THESE STEPS ARE A WARRANTY CONDITIONFollowing the steps and grits above — with Germa-Tech abrasives — is a condition of product warranty, not a suggestion. P-grades are only comparable within a controlled range: a recent claim traced to an ungraded brand’s “P320” that cut like a true P240, leaving scratch in the primer that showed through the finished clear. The part numbers above are graded and tested for compatibility with this product and this process — which is what makes a fault assessable: once non-Germa-Tech product has been used, what touched the panel can no longer be verified, and issues arising cannot be fairly assessed. Refer to the GERMA-TECH APPLICATION STANDARD.

10STORAGE, SHELF LIFE & PACKS

Storage life (unopened)Up to 36 months unopened — SUBJECT TO correct storage: a cool, dry place below 20 °C, out of direct sun. Heat is the biggest killer of paint in the tin: stock stored or transported in hot vehicles, tin sheds, shipping containers or direct sunlight loses life fast whatever the date on the tin, and that is where most premature failures start. Storage life is an optimal guide, not a promise that survives a hot shed.
Once the seal is brokenOnce the seal is broken the clock starts, and how you store it sets the pace. This product: 14 DAYS once the seal is broken, then discard.
All hardeners: 14 days once opened — then discard. Hardener is sealed without air; the moment air enters it starts to deteriorate. A part-used tin resealed tight lasts the 14 days; a loose lid does not.
StorageStore indoors in a cool, dry place below 20 °C, out of direct sunlight, with the lid sealed tight after every use. Never store or transport in heat — not in a tin shed, a shipping container, a hot van or a sunlit rack.

13STANDARD NOTES — THE SAME ON EVERY SHEET IN THIS SET

Standard inclusions are controlled: each note applies to every product in its named set, enforced at build. They cannot drift onto some sheets and off others.

14PRODUCT-SPECIFIC NOTES

WARNINGS CARRIED FORWARD FROM THE PREVIOUS SHEETA flash of is required between each coat, flash off time should be adjusted +/- depending on air temperature. Fast and Slow hardeners and reducers can be used in extreme cold or extreme heat.
A flash time of 15-20 min is required before commencing the bake.
AMBIENT TEMPERATURE — WHY EVERY TIME ON THIS SHEET MOVESEvery time on this sheet — flash-off, drying, pot life, the recoat window — is quoted at 20-23 °C, and every one of them moves with temperature, because the two things that set them, solvent evaporation and chemical cure, are both driven by heat. As a working rule cure rate roughly doubles for every 10 °C rise: at 30 °C the times run at about half; at 15 °C they stretch to nearly half speed. Judge by panel temperature, not air temperature — a panel in sun or fresh out of the booth is far hotter than the shed.
HOT WEATHER (above 30 °C): everything shortens. Flash-off comes down, pot life comes down, and the recoat window closes early. Move to the SLOW hardener and slow or extra-slow reducer so the film has time to flow and release solvent — spraying standard speeds in heat is the fast road to dry spray and solvent boil.
COLD WEATHER (below 20 °C): everything stretches. Flash-off gets LONGER — the most common winter mistake is coating over a film that looks flashed but has not released its solvent, which traps it under the next coat and comes back as fry-up, dieback or runs. Move to the FAST hardener, and extend every flash. Below 15 °C standard 2K cure effectively stalls — bake the job, or wait for heat. Cold does not extend the recoat window in proportion either: contamination, moisture and flash rust run on the clock regardless of temperature.

15GOOD TO KNOW — WHAT WE GET CALLED ABOUT

16TROUBLESHOOTING

DEFECTWHAT YOU SEEWHY IT HAPPENEDFIX
Thermal cracking over heavy basecoatCracking or crazing in the clear, typically appearing days or weeks after the job, almost always on blacks and dark colours, often after the vehicle has sat in the sun.Too much total basecoat film — often from using basecoat as a ground coat under the colour. Any ground coat forms part of the 2-3 coat maximum and the film build limit; it does not get its own allowance. The overloaded basecoat dries late and keeps moving under the cured clear, and dark colours soak up heat — the heavy film expands and contracts at a different rate to the clear until the clear delaminates or cracks. It is a film-build failure underneath, not a clear coat fault.There is no rescue coat — the affected panels must be sanded back past the failed film (usually to primer), refinished at correct film builds and properly flashed.
Hardener bloom and moisture-struck hardenerhardener goes cloudy, thick or crystalline in the tin, or the clear comes out hazy and slow with tiny bubbles in cold damp weatherisocyanate hardener reacting with moisture - the tin left open, damp air lines or a wet gun, or cold humid conditions during applicationdiscard hardener that has gone cloudy, crystalline or gassy - it will not cure the film; re-mix from fresh material and, if the panel is already sprayed, cure it out, sand back and refinish
Blushinga milky, hazy or white cast through the film, worst in hot or humid weather and on fast-drying worksolvent flashing off so fast it chills the film and pulls moisture out of the air into it - hot shop, high humidity, or a reducer or hardener that is too fast for the daywhile wet, a coat with retarder in it will often pull it back; once cured, sand the affected film back and refinish with the correct reducer speed
Solvent popsmall open craters or burst blisters through the film, usually only obvious after the bake or once the panel has cooledsolvent trapped under a skinned-over film - flash time cut short, coats laid on too heavy, too many coats, or the panel put into the bake before the final flash was donelet the film cure right out, then sand the popped area back to a sound film and refinish; if it has gone through to the undercoat, sand back to the undercoat, re-prime and refinish
Die-back and gloss lossthe finish looks right coming out of the booth and then dulls off over the next hours or dayspolished or handled before the film had cured, film built too heavy, flash between coats too short, wrong reducer or hardener for conditions, or poor booth air movementlet it cure, then compound and polish; if the gloss will not come up, sand and respray
Dirt and dust inclusionhard specks sitting in or under the cured film, felt with the back of the hand before they are seendust pulled in during application - panel not tacked off, static on plastic parts, dirty booth filters, contaminated air, overalls or gun, or crystallised additive poured straight from the tinsurface nibs come out after cure with P1500 working to P3000 then polish; anything embedded through the film has to be sanded and refinished
Water spottingdull rings or spots where water droplets have sat and dried on the finish, most often on a fresh jobwater landing on a film that has not fully cured, washing in direct sun, or a car put out in the weather before the film has hardenedcompound and polish; if the marks have etched in, sand P1500 to P3000 and polish, or sand and refinish
Soft film and slow curethe film stays soft, marks under a fingernail or a mask edge, clogs the paper when sanded and will not polish upwrong or short-measured hardener, mixing beyond pot life, spraying too cold, bake cut short or started before the flash was finished, or a drying additive used where a hardener is neededgive it a full bake cycle and re-check; if it is still soft the film has to come off back to a sound layer and be redone with the correct mix
AUSTRALIAN CONDITIONSAbove 30 °C ambient, move to the slow hardener and slow reducer and expect flash-off to shorten — dry spray and blushing are what a standard system gives you through a hot afternoon. Below 15 °C, air drying is not recommended: bake. In coastal and high-UV areas do not shortcut the epoxy step on bare metal.

17HEALTH & SAFETY

ISOCYANATE — AIR-SUPPLIED RESPIRATOR REQUIREDThe hardener for this product contains isocyanate. Spray only in a booth complying with AS/NZS 4114:2020, using air-supplied respiratory protection — a cartridge respirator is not adequate protection against isocyanate mist. Workers exposed to isocyanates require health monitoring under the model WHS Regulations (Schedule 14) and equivalent state legislation. Refer to the Safe Work Australia Model Code of Practice: Spray painting and powder coating. Read the Safety Data Sheet before use.

v2.302.09.2026Reissued on the current Germa-Tech technical data sheet format. New in this issue: a quick-reference card, the hardener and reducer selection gauge, the coating thickness stack, the recoat-window recovery procedure, and a product-specific troubleshooting table. Bake schedules are now stated as metal temperature.

18CARE OF THE COATING

CARE OF THE COATING — CONDITIONS OF THE WARRANTYFirst 12 weeks: hand wash only, pH-neutral automotive wash, soft mitt; no machine or brush washes, no wax, polish or cutting, no car covers; never leave fuel, brake fluid or water spotting to sit. No ceramic, glass/quartz coating or paint protection film for 12 months — sealing a maturing film traps solvent. Contaminants: bird and bat droppings, sap, insect residue, fuel and fallout etch the film — remove as soon as seen; etching left on is damage, not a defect. Cleaning: pH-neutral shampoo and fresh-water rinse; never dishwashing detergent, household cleaners, abrasive pads or strong solvents on the cured paint film; pressure washers fan tip, 30 cm minimum, never at edges or chips. Wash-down: passenger vehicles at least fortnightly (weekly in coastal, industrial or high-fallout exposure); fleet units weekly, more in heavy work, with a monthly walk-around and a wash-down register; any vehicle immediately after salt, fertiliser, chemicals, concrete dust, fuel or fallout; architectural and stationary work every 3 months (monthly coastal/industrial) with a maintenance register. Wax and polymer sealants may go on from 12 weeks, once cured. Breaches: inspect and touch up promptly — corrosion from any chip, scratch or breach, repaired or not, is never a coating defect.
