Product Information
Full details
U-Pol Gravitex is an essential automotive coating designed for DIY enthusiasts and professionals looking to protect vehicle lower panels and wheel arches from stone chips, salt, and environmental corrosion. This high-build formula offers a robust barrier that preserves the integrity of your vehicle's paintwork while providing a professional, textured finish. The primary caveat is that while the product is overpaintable, it requires proper surface preparation and appropriate drying times to ensure optimal adhesion and a seamless final look.

FAQs
Do I need to prime the surface before using Gravitex?
Yes, if you are applying to bare metal, you must use a suitable etch or epoxy primer to ensure proper adhesion and long-term rust protection.
Can I apply Gravitex with a brush?
Gravitex is designed primarily for spray application. Using a brush will not yield the intended textured finish and may result in an uneven protective layer.
How long should I wait before painting over it?
Refer to the product label for specific temperature-based drying times, but generally, allow the coating to cure for at least 24 hours in a well-ventilated area.
Is this product waterproof?
Yes, once cured, Gravitex forms a water-resistant, protective barrier that helps prevent moisture from reaching the metal substrate.
Can this be used on plastic bumpers?
It is generally safe for plastic surfaces, but ensure you use a plastic adhesion promoter first to ensure the coating bonds correctly.
Troubleshooting
Coating is peeling or flaking off
This is usually caused by inadequate surface preparation; ensure all wax, oil, and loose debris are removed with a degreaser before application.
Texture is uneven or splattered
Adjust the air pressure on your spray gun. Lowering the pressure often creates a heavier texture, while higher pressure results in a smoother finish.
Topcoat is bubbling over the Gravitex
Ensure the Gravitex has fully cured. Applying a topcoat too early can trap solvents in the base layer, leading to bubbling.

Setup, Compatibility & Care
To achieve the best results, ensure the application surface is clean, dry, and free from grease or wax. If applying over bare metal, always use an appropriate anti-corrosion primer first. The product is designed to be applied using an undercoating spray gun. After application, allow the coating to cure according to the technical data sheet before attempting to apply any topcoat. Regular maintenance involves simply washing the treated areas with standard automotive shampoo; the durable nature of Gravitex means it does not require specialized cleaners.
