U-Pol GRAVITEX is a professional-grade stone chip protector designed for automotive enthusiasts and body shop technicians who require a durable, long-lasting barrier against road debris and corrosion. It is an ideal solution for shielding high-impact underbody areas, offering a robust finish that maintains the integrity of vehicle panels. However, users should note that as an industrial coating, it requires proper preparation of the surface and specific spray equipment to achieve the optimal, factory-like texture.

Yes, as long as the existing paint is sound, clean, and has been scuffed with a fine-grit abrasive to promote mechanical adhesion.
No, it is designed for use straight from the 1000 ml bottle using a standard suction feed or Schutz-style undercoating gun.
Drying times depend on ambient temperature and thickness, but it is generally recommended to wait until the coating is touch-dry and stable before applying topcoats.
While intended for underbody and exterior protection, it can be used for interior floor pans, provided it is top-coated to seal the finish.
While technically possible for small touch-ups, spray application is strongly recommended to achieve the professional textured finish and uniform thickness.
Reduce the thickness of each individual pass and allow for shorter flash-off times between coats.
Check air pressure settings on the applicator gun and ensure the canister is agitated thoroughly before use.
Ensure the surface was sanded and properly degreased prior to application; ensure bare metal is primed.
Before application, ensure the substrate is free from grease, wax, and loose paint by using a high-quality degreaser. If applying to bare metal, apply an appropriate etch primer first to ensure maximum bond strength. GRAVITEX is compatible with most standard basecoat/clearcoat systems once fully cured; verify compatibility with your specific paint brand if applying color immediately. To maintain the finish, simply clean with mild automotive soap; avoid abrasive chemicals that could degrade the cured polymer layer.
