Reasonably good results can be obtained if one of the following is used, but note that chrome is not an "approved" substrate:

For radiator grills: Sand the surface as well as possible, apply two coats of GRIP#4 (GRIP/AL), allow to dry then apply RAPTOR.

For more demanding substrates, such as bumpers: Sand the surface as well as possible, apply epoxy primer (following primers guidelines), then apply RAPTOR.

Abrade surface with P80-P180 grit sandpaper and apply 1-2 coats of ACID#8 Acid Etch Primer (ACID/AL). Allow to dry for 15-20 minutes before applying RAPTOR. If ACID#8 is not available, any 2K DTM or Epoxy Primer can be used to prime bare metal (follow top coat directions for primer).

Clean the aluminium with a wax and grease remover and sand with P180 grit sandpaper. Apply one to two coats of ACID#8 Acid Etch Primer (ACID/AL) and use GRIP#4 Universal Adhesion Promoter (GRIP/AL) for hard to reach areas. Allow to dry 20 minutes before applying RAPTOR.

The durability of RAPTOR is strongly linked to its high film build. By adding reducer the film build will decrease and therefore some of its durability characteristics will decrease, although only slightly.

Yes, RAPTOR can be applied to both steel and alloy wheels. The preparation is as follows: sand with P80-P180 grit, use ACID#8 Acid Etch Primer (ACID/AL) or epoxy primer over exposed bare metal, and apply.

RAPTOR can be used on most plastic without much preparation. Abrade the plastic with P180-P240 grit sand paper or red scotch and then apply an adhesion promoter, like GRIP#4 (GRIP/AL). Wait about 20 minutes before applying RAPTOR.

If the wood has been pre-treated or painted, clean the wood of any contaminants. If cleaned with water, allow to dry first. Lightly sand any painted areas. Once dry, apply RAPTOR.

Blow off the surface to remove dust. Light sanding is “OK” but generally RAPTOR can be directly applied to wood and plywood substrates.

As long as the concrete is clean, dry, and free of oil, you can apply RAPTOR directly to concrete. If concrete is sealed, a rotary floor sander can be used to abrade surface. Any petroleum based surface contaminates should first be cleaned with a suitable cleaning solution to neutralise the contamination,

Scuff the surface with P100-P120 grit sandpaper and degrease before applying RAPTOR. An adhesion promoter, like GRIP#4 (GRIP/AL) can be used in hard to reach areas and for optimum adhesion.

Yes, it can be applied to both solvent and water borne basecoat. Follow basecoat manufacturer’s drying times prior to over coating.

Clean the surface with wax and grease remover and scuff the surface with red / maroon scuff pad. Re-clean the surface before applying RAPTOR.

Follow the epoxy primer manufacturer’s recommendations for top coating. Generally, after primer is dry / cured, sand surface with P280-P360 grit sandpaper, or whatever grit recommended by the manufacturer for top coat application, blow off, and re-clean if necessary before applying RAPTOR.

Clean the surface with wax and grease remover and lightly sand with P180 grit sandpaper before applying RAPTOR.

Ferrous chloride is a salt and will readily absorb moisture. Most coatings over salts may suffer from early blistering and/or corrosion of the substrate. It is not recommended that RAPTOR be used in this situation. Strip away the ferrous chloride either chemically or mechanically, and then degrease the substrate. Clean the surface before applying RAPTOR.

U-POL has not tested RAPTOR on rubber; however many flexible vehicle parts are actually plastics, like TPO, EDPM or PP.

RAPTOR is a water tight coating once fully cured and can be used for many marine applications. Let RAPTOR cure completely for approximately 72 hours before immersing in water.

RAPTOR will also hide a multitude of problems, like crazing, pitting and scratches. Sand the crazed gel coat with P100-P120 grit sandpaper before applying RAPTOR. First, repair the damaged gel coat with FIBRAL (FIB/2) or SMC bonding filler (SMCB/AL - black or SMCW/AL - white) to seal the surface.


Applying RAPTOR with a roller will produce very good textures. Care must be taken when applying with a roller because softness will occur if RAPTOR is applied too thickly. Make sure that a medium coat is applied with the roller so that the RAPTOR can cure and harden so scratch resistance will still be maintained.

Use a coarse textured foam roller (such as one used for heavy textured coatings) for the best finish, but other types of rollers can be used depending on the final texture desired.

Depending on the texture desired, once reduced, RAPTOR can generally be applied with a nozzle set from about a 1.4 up to a 2.0. Once it is thinned to a maximum of 20% it is possible to spray it through a smaller nozzle set (1.2 - 1.3) however, the film build will be pretty thin and it may not have the same chip resistance that it does when applied with a larger nozzle set. In reality, it all depends on the look, finish and texture that you want to achieve.

Typically, 3-4 bar is recommended. Higher or lower pressure can also be used, but it’s recommended you spray a test panel first to make sure the texture is what you are looking for.

The recommended RAPTOR application is 2-3 coats with a 60 minute flash time between coats. If further build is needed, it is recommended to carry this out in several applications. For instance, apply the first 2-3 coats, bake or allow 24-hours to dry and then apply another 2-3 coats, etc. The key is to allow as much solvent to evaporate from each layer before adding subsequent layers. If the process is carried out too fast, RAPTOR may remain soft and take longer to fully cure.

RAPTOR can generally be re-coated after 24 hours. Scuff it with a red scuff pad, clean with wax and grease remover, apply the next coat of RAPTOR.

Cured RAPTOR can easily be touched up. Just clean the surface, sand and featheredge a few inches into the surrounding area, re-clean, and mix and apply as usual. No need to prime again unless you sand down to bare metal. Remember, if it's been more than 5 hours since the last coat of RAPTOR has been applied, allow RAPTOR to cure for 24 hours, then lightly abrade and apply additional coat(s).

RAPTOR is a coating made to last, so it is difficult to remove once cured. Once RAPTOR is cured, remove by sanding it off with P80 grit sandpaper either down to the original substrate or to bare metal. Then, respray the surface with another coating, like OEM paint colours.

Do not allow RAPTOR to come in contact with water for at least 72 hours.

The average thickness for RAPTOR is 200-250 µmper coat. Applying 2 medium coats of RAPTOR is recommended. Measurements are approximate and are dependent on the application method.

One RAPTOR 4L Kit will cover approximately 12 sq metres at recommended film build (3 sq metres / litre).

It is not recommended for application below 5oC. When RAPTOR is applied at the lower temperatures, the dry and cure time is significantly extended.

Yes, 30 minutes at 60oC.

Yes, RAPTOR can be used for both.

A 6 HP compressor that generates 10 bar line pressure should provide sufficient air supply, but is dependent on the application equipment / gun (Schutz type or gravity feed HVLP) used to apply the RAPTOR.

Mix Ratio

A. Volume - 3 parts RAPTOR – 1 part hardener – 10% colour.

B. 100g RAPTOR - 30g hardener and - up to 10g tint. Refer to online technical datasheet for additional quantities.

Yes, RAPTOR can be reduced up to 20%. When reducing RAPTOR, use a urethane based reducer.

Tinting RAPTOR

Yes, RAPTOR has been designed to be tinted with standard solvent-borne base coats.

If the colours are quite close to each other, reapply with the RAPTOR tinted to the correct shade. Please note that, if RAPTOR should chip under extreme duty conditions, the underlying colours will show through. If the colours are not close, it will be necessary to sand and re-apply

For best colour match results, tintable RAPTOR requires a solvent colour. Various paint lines may have stronger or weaker toners so final colour may vary. Ask your paint supplier to leave any binder or balancer out of the formulation if possible so it is pure pigment.

Yes, tint can be added to the black or white kits as well. If you're looking to match a colour code, it may be hard to do this way. Suggested that you conduct a test spray out to determine if the colour and look is acceptable prior to general application.

Metallic toners can be used however, you may experience "metallic burying" and the RAPTOR may not have the exact look that you are attempting to match. Our suggestion is to conduct a test spray-out before committing to the whole project.


Most paint manufacturers provide proprietary matting agents that are used in other 2K products, and these are suitable for use in RAPTOR. Follow the manufacturer’s recommendations. Please note this may reduce RAPTOR’s flexibility.

RAPTOR dries as a hard satin gloss finish. It won’t attract dirt and is easy to clean.

On its own, RAPTOR is not skid resistant, or non-slip. For a non-skid surface on walkways, mix RAPTOR Traction – Slip-Resistant Additive (RLTR/SM) into to the final coat before applying.

Mix RAPTOR Traction – Slip-Resistant Additive (RLTR/SM) into the final coat before applying for a textured grip finish. RAPTOR Traction will only work through a standard application gun.

There are two ways to get a smoother finish. 1). Turn up the pressure on the gun. 2). Add thinner as per the technical datasheet instructions. For instance, you could use an HVLP gravity fed gun with a 1.6-2.0mm nozzle set up. Add 15% urethane reducer when mixing RAPTOR. Set your gun at 2 bar. At a distance of about 15cm, spray the first coat as an even wet coat. After flashing, reduce the pressure and material flow to achieve a fine mist for the second coat.

Allow 24 hours for RAPTOR to fully cure.

RAPTOR can be topcoated, but generally, it's not needed. RAPTOR dries to a semi-gloss/eggshell finish, which most people find to be plenty of gloss. Clearcoats do not have the same level of durability as RAPTOR and are more likely to chip under heavy duty use.

Lightly abrade fully cured RAPTOR with a grey scuff pad. U-POL 2K clearcoats, like S2080SR, use the same resin system as RAPTOR so U-POL clearcoats will give the best results

Technical Properties and Chemical Composition

Activated RAPTOR Black and Tintable are NOT isocyanate free because the hardener used does contain isocyanates

The typical Shore D Hardness Value for fully cured RAPTOR is 85.

RAPTOR is a thick urethane coating and does not contain any rubber. The texture is controlled and created by the application. Lower air pressure gives a rougher texture, while higher air pressure gives a thick orange peel effect. Unlike most of the other DIY bed liners out there, RAPTOR is 2-part urethane product, which gives great UV stability and impact resistant without the use of additives like rubber. 

100°C. At sustained temperatures above 100oC, some softening could occur

RAPTOR can withstand some exposure to petrol. If the area will be submerged in petrol, RAPTOR should not be used, as there may be some surface softening from prolonged exposure.

RAPTOR is not an insulator. Some installers will apply RAPTOR on the exterior in White to deflect heat (simply because of colour). The temperature resistance of RAPTOR is -18oC to 100oC, so it's not recommended for application anywhere there could be excessive heat, like the motor or exhaust.

We have had some users apply RAPTOR as a sound dampener with success, but it has not been tested by U-POL.


The life of RAPTOR once applied can depend on application method, film build, quality of preparation and substrate. We have tested RAPTOR against other products in the market and have laboratory test data which proves better performance. When applied correctly, RAPTOR will last for years and is very easy to repair if necessary. It has excellent U.V. stability and will not fade. The RAPTOR Land rover we have done in the UK was painted in 2015 and has travelled all over the UK on the road. It still looks as good as the day it was painted, with no defects.

The shelf life of an unopened RAPTOR kit is 2 years from the date of manufacture.

A RAPTOR Kit has a full 4L of sprayable product, where most competitors only provide around 2L of product in a kit. The RAPTOR Kit is designed so that one kit will cover an average truck bed.
