Autotek: understand the range before choosing
Autotek is a Tetrosyl automotive-paint brand aimed at DIY and professional repair work. Tetrosyl's official range description covers primers, gloss, satin and matt topcoats, lacquers, wheel and bumper finishes, high-temperature coatings and stoneguards. The products here closely follow that identity, so this page is organised as a coating-system guide rather than a general maintenance collection.
AutoMotoPart currently lists 51 Autotek items. The largest Autotek groups are 50 maintenance entries, 1 autotek engine enamel gloss black 500ml entry. Autotek totals can change, so a category count is orientation rather than proof that a particular reference suits a vehicle, workplace or job. The exact Autotek listing, its current technical information and the item in front of you must agree.
What the Autotek page actually covers
| Product group in this range | Current entries | Selection focus |
|---|---|---|
| Maintenance | 50 | Confirm substrate, preparation, product role, colour or finish, compatible next layer, application method and safety data. |
| AUTOTEK ENGINE ENAMEL GLOSS BLACK 500ML | 1 | Treat the isolated engine-enamel label as a specific 500ml gloss-black coating, not an alternative category system. |
Fifty entries sit under the broad maintenance label, while the individual names show a complete preparation-to-finish assortment. Primer appears in ten titles and paint in thirty-one; 500ml is frequent, with smaller 400ml colour aerosols and 250ml caliper or VHT formats. Preserve each qualifier—plastic, etch, zinc, high-build, wheel, engine or stoneguard—because it identifies the coating's intended role more usefully than colour alone.
Build a reliable shortlist
Create a coating schedule before sanding. Write down the substrate, retained coating, defect depth, corrosion status, flex or heat exposure, target colour and sheen, and every proposed layer. Then check the technical directions for compatibility, preparation, recoat window and cure. The table below turns that schedule into selection evidence.
| Check | Why it matters | Useful evidence |
|---|---|---|
| Base material | Steel, non-ferrous metal, plastic and filler can need different adhesion routes | Clean exposed substrate and current Autotek substrate statement |
| Defect scale | Scratches, pinholes, corrosion and structural loss are not one repair | Inspection after cleaning, with unsafe damage repaired before coating |
| Primer function | Etch, zinc, plastic, filler and high-build names indicate distinct purposes | Exact product data and compatibility with retained paint and topcoat |
| Colour and sheen | A colour family can be offered as gloss, satin, matt or effect finish | Vehicle or project code, test panel and approved finish system |
| Service exposure | Heat, stone impact, fuels or flex change coating requirements | Component duty and the product's stated limits and exclusions |
| Application controls | Film build and solvent release depend on coats, timing and environment | Label, safety data, temperature, airflow and measured working conditions |
If the manufacturer information does not show that two layers can be combined, do not use a quick test on the vehicle as proof. Prepare a separate test panel representing the substrate and retained finish. Watch for softening, lifting, crazing, loss of adhesion or sheen change through the stated drying period before committing to the repair.
General, high-build and filler primers
Autotek general primers appear in grey and white, while high-build versions add red to that choice and a separate filler primer is listed. Primer colour can influence coverage or inspection, but its main selection question is whether it belongs on the exposed substrate and beneath the chosen colour coat. Apply it over a uniformly prepared surface, not across wax, silicone, loose corrosion or feather edges that still lift under light abrasion.
High-build material can provide more film for blocking limited sanding marks, but excess film is not a substitute for flat preparation. Follow the permitted coat number and flash time, then allow the layer to dry before guide coating or sanding as directed. Breaking through at an edge can expose a different substrate and may require a local return to the correct primer rather than another heavy coat over the entire panel.
Etch, zinc and plastic primer decisions
Etch primer is a specialist route for stated bare-metal conditions, zinc primer has its own protective and system role, and plastic primer addresses adhesion to permitted rigid plastics. None should be selected merely because the substrate is difficult. Identify the alloy or plastic where possible and read exclusions. Galvanised parts, aluminium and unknown plastics can react differently to cleaners and primers.
For plastic, remove old dressings and mould-release contamination without attacking the material. Test an inconspicuous area and consider flexibility and heat. For metal, eliminate active corrosion as required and protect cleaned surfaces from fingerprints and moisture. Do not trap rust beneath zinc-labelled material or spray etch products over incompatible filler, putty or retained paint unless the current instructions expressly allow it.
Topcoat colour, effect finishes and lacquer
The colour selection includes named fleet or vehicle shades, a RAL blue, black and white in different sheens, aluminium, chrome-effect and fluorescent green. A generic name cannot guarantee a repair match: batch, substrate, primer colour, film thickness and ageing of the adjacent surface all influence appearance. Spray a prepared test card and view it in relevant lighting before the final panel.
Clear lacquer, matt lacquer, wheel lacquer and petrol-resistant lacquer are separate references. Determine whether the colour coat is designed to remain unlacquered or to receive one of these systems, and whether the final sheen agrees. Apply within the stated recoat window. A clear layer cannot correct poor colour match or solvent reaction underneath, and a matt layer needs uniform technique because polishing can change its sheen.
Wheel, caliper, engine and high-temperature coatings
Autotek wheel products include alloy and gloss-black colour plus a dedicated clear lacquer. Remove the wheel where the safe procedure requires it, clean brake dust and contamination without damaging the substrate, and mask tyre, valve, hub face, nut or bolt seats and mating surfaces. Corrosion or cracking needs assessment before paint; cosmetic coverage is not a wheel repair.
Caliper colours, engine enamel and VHT black or silver serve different temperature and chemical environments. Confirm the permitted component and temperature range from the exact product. Keep coatings away from friction material, disc or drum tracks, pistons, seals, bleed screws, hoses, sensors and sliding interfaces. Curing requirements may involve time or heat stages; do not return the part to service until the specified process is complete.
Bumper, trim, stoneguard and safe spraying
Bumper and trim aerosol appears in black and dark grey, while stoneguard is listed in several colours. Determine whether the existing part is painted plastic, textured plastic, flexible trim, a sill or underbody area, and whether a topcoat is intended. Reproduce original drain holes, seams and identification rather than burying them beneath a thick cosmetic layer.
Set up aerosol work to control people, vehicles, dust, airflow and ignition sources. Read the safety data before abrading old coatings or using paint stripper because the substrate and waste may introduce additional hazards. Wear the specified protection, prevent vapour migration and collect contaminated masking or abrasive material. Store cans upright as directed and never puncture, incinerate or heat them to change spray pressure.
From identification to a checked result
| Stage | Good practice for this range | Mistake to avoid |
|---|---|---|
| Survey | Identify substrate, retained coating, damage, exposure and required finish | Using colour as the first and only Autotek decision |
| Design system | Choose compatible cleaner, repair, primer, colour and lacquer stages | Mixing specialist primers without a documented route |
| Prepare | Remove contamination and unstable material, feather edges and mask interfaces | Painting over silicone, corrosion or a braking surface |
| Apply | Use controlled coats, distance, overlap and intervals from the directions | Hiding defects under excessive high-build film |
| Cure and inspect | Confirm adhesion, sheen, coverage and service readiness before assembly | Exposing fresh engine or caliper paint to heat too early |
Retain the Autotek product codes, batch details where shown and the order of layers. A useful job record also notes substrate, preparation abrasive, temperature and recoat times. If a finish later lifts or changes sheen, that evidence helps isolate preparation, compatibility or curing rather than prompting another unsupported layer.
Reading real Autotek references
The Autotek names below are examples from the current range and show why the complete description matters. They are not universal Autotek recommendations and should not be treated as a fitment list. Within Autotek, a shared family word can conceal a different dimension, connector, material, pack format, operating condition or installation side.
| Example listing | What to verify beyond the name |
|---|---|
| Caliper Paint - Blue - 250ml | 250ml blue caliper finish, permitted metal, preparation, excluded brake areas and cure |
| Caliper Paint - Black - 250ml | 250ml black caliper finish, component condition, application method and service readiness |
| Caliper Paint - Red - 250ml | 250ml red caliper coating, substrate, fluid contamination, coats and temperature exposure |
| Caliper Paint - Yellow - 250ml | 250ml yellow caliper coating, masking, colour test, film and curing sequence |
| VHT Paint - Black - 250ml | 250ml black VHT product, stated component and temperature range, preparation and cure |
| VHT Paint - Silver - 250ml | 250ml silver VHT reference, substrate, permitted heat exposure and reassembly timing |
| Autotek Bumper & Trim Aerosol Paint - Dark Grey - 500ml | 500ml dark-grey bumper/trim aerosol, plastic type, retained coating and flexibility |
| Autotek High Build Primer - Grey - 500ml | 500ml grey high-build primer, defect depth, substrate, topcoat compatibility and sanding |
The opening examples alone span brush or specialist caliper products, VHT coatings, plastic trim aerosol and high-build primer. Their pack size and black, grey or bright colour do not connect their uses. Keep the exact Autotek name beside prepared parts so a high-temperature can is not confused with ordinary gloss paint at the bench.
Common errors around Autotek products
- Selecting Autotek primer by colour without identifying its substrate and system role.
- Using high-build primer to conceal deep filler failure, rust perforation or structural damage.
- Spraying plastic primer onto an unknown polymer without checking compatibility.
- Expecting a named colour or can cap to match aged adjacent paint without a test panel.
- Applying clear lacquer automatically over a colour not designed for that lacquer system.
- Coating wheel hub faces, brake friction areas, studs, threads, seals or sensors.
- Treating engine enamel and VHT paint as interchangeable temperature specifications.
- Handling, assembling or heating a coated component before its stated cure is complete.
Autotek questions and answers
Q: What dominates the Autotek range?
A: Automotive primers, colour aerosols and lacquers dominate, supported by wheel, caliper, engine, VHT, trim and stoneguard coatings.
Q: Does primer colour define its purpose?
A: No. Substrate and coating-system compatibility come first; colour is only one secondary property.
Q: When is high-build primer appropriate?
A: Use it only for the limited preparation defects, substrates, film build and topcoats stated in its directions.
Q: Can filler primer replace body filler?
A: No. It cannot bridge structural damage or deep defects beyond its specified coating role.
Q: Is etch primer suitable for every bare metal?
A: No. Identify the metal and check the current Autotek instructions and the layers that follow.
Q: Why use plastic primer?
A: It is an adhesion stage for the permitted plastics, which still require correct cleaning, testing and a compatible topcoat.
Q: Will a named colour match an old panel?
A: Not necessarily. Ageing, batch, primer and application affect appearance, so use proper identification and a test card.
Q: Does every colour coat need clear lacquer?
A: No. Follow the specified system and choose the correct gloss, matt, wheel or specialist lacquer only where required.
Q: Can wheel paint cover corrosion?
A: It can colour a prepared surface but cannot make a cracked, weakened or badly corroded wheel serviceable.
Q: Where must caliper paint be kept away from?
A: Protect friction surfaces, discs or drums, seals, hoses, pistons, sliders, sensors and bleed hardware.
Q: Are engine enamel and VHT identical?
A: No. Use the exact component, temperature and curing information for the selected reference.
Q: What should be recorded after an Autotek repair?
A: Keep product codes, layers, substrate preparation, conditions, intervals, test result and cure completion.
