U-Pol Gravitex is a professional-grade stone chip protection coating designed for automotive enthusiasts and body shop technicians looking to shield their vehicle's vulnerable panels from gravel, road salt, and environmental debris. The primary benefit of this product is its ability to create a tough, durable, and textured barrier that effectively resists impacts and corrosion. One important caveat is that while the formula is overpaintable, users must ensure the surface is properly prepped and the coating is fully cured before applying a topcoat to ensure proper adhesion and color matching.

To achieve the best results with U-Pol Gravitex, ensure the application surface is clean, dry, and free of grease, wax, or loose rust. Use a degreaser before application to ensure maximum bond. The product is intended for use with a dedicated undercoating suction feed gun. When applying, maintain an even distance from the panel to ensure uniform texture. Allow for sufficient drying time—typically 24 hours depending on ambient temperature and humidity—before attempting to sand or topcoat the surface. Store the container in a cool, dry place and ensure the lid is tightly sealed to prevent the contents from skinning or thickening.
