The U-Pol Gravitex Stone Chip Protector in Grey is designed for automotive enthusiasts and professional body shops seeking a durable, factory-finish coating for chassis and lower body panels. This professional-grade protector excels at shielding vehicles from stone chips, salt, and road debris while remaining fully overpaintable to match your vehicle's color. A significant caveat is that it requires a dedicated Schutz-style spray gun for application, meaning it cannot be applied effectively with standard brushes or rattle cans.

No, this product is designed specifically for spray application to achieve the correct texture and thickness.
Depending on ambient temperature, it is generally ready to be overpainted within 1 to 2 hours of application.
No, the product is supplied ready-for-use and should not be thinned.
It provides a barrier against moisture and road salt, but it is not a rust-converting primer. Existing rust must be treated before application.
The grey color is a finish, but it is designed to be covered with a topcoat. It may fade or chalk if left exposed to UV light for extended periods without paint.
Reduce the air pressure at the spray gun or increase the distance from the panel to allow the product to 'splatter' slightly.
Increase the distance from the panel and apply thinner, lighter coats with a brief flash-off time between them.
Ensure the surface was sanded properly and degreased with a wax and grease remover before application.
To apply U-Pol Gravitex, you must use a standard Schutz-type air-powered spray gun. Ensure the surface is clean, dry, and free of wax, grease, or loose rust before application. For best results, sand the substrate with P180-P240 grit sandpaper to ensure optimal mechanical bond.
Compatibility Note: Always conduct a test spray on a scrap panel to adjust your gun's air pressure and fluid settings to achieve your desired texture before spraying the vehicle. Clean the spray gun immediately after use with a suitable solvent, as the product is designed to harden permanently once cured. Store the canister in a cool, well-ventilated area away from direct sunlight.
