FAQs

Does this kit include the air compressor?

No, the kit includes the application gun but requires an external air compressor to operate.

Can I paint over this coating?

Yes, U-Pol Gravitex Plus is specifically designed to be overpaintable with most automotive topcoat systems.

How long should I wait before driving the vehicle?

While the coating is touch-dry relatively quickly, it is recommended to allow at least 24 hours for a full cure before exposing the vehicle to road conditions.

Is the finish smooth or textured?

The finish texture can be adjusted based on the air pressure and your technique with the spray gun.

Why are there both black and white bottles?

The two colors allow you to choose a base that best suits your final paint color, ensuring better coverage and color matching.

Troubleshooting

Coating is too thin or watery

Ensure the air pressure is set correctly and the bottle is shaken thoroughly before use.

Gun nozzle clogging

Clean the nozzle immediately after use and ensure that the mixture is not left to sit in the gun for extended periods.

Poor adhesion to the surface

Verify that the surface was properly cleaned and abraded (scuffed) before application to ensure the coating has a surface to bond with.

Pros and Cons

Pros

  • Comprehensive kit includes all necessary units and application hardware
  • High-build formula provides superior impact resistance
  • Overpaintable for professional aesthetic results
  • Two-color options allow for contrast or better matching under paint
  • Extremely durable against road salt and moisture

Cons

  • Requires an air compressor for the included gun
  • Not suitable for use without proper protective equipment
  • Requires significant surface preparation for optimal adhesion
  • Large 12-litre volume is best suited for whole-vehicle projects

Setup, Compatibility & Care

Before starting, ensure the vehicle surface is clean, dry, and free from loose rust or contaminants. Mask off areas that do not require coating to prevent overspray. Connect the provided application gun to an air compressor and test the spray pattern on a piece of cardboard to achieve the desired texture before applying it to the vehicle. The coating can be overpainted once it has fully cured, which generally takes 24 hours depending on ambient temperature. Clean the application gun thoroughly with appropriate solvent immediately after use to prevent the coating from hardening inside the nozzle.
