U-Pol Undercoating
U-Pol Undercoating: Professional-Grade Protection for Every Underbody
When it comes to shielding a vehicle's most vulnerable surfaces from the punishment of daily driving, few names carry as much credibility as U-Pol. A recognized world leader in automotive refinishing products, U-Pol has built its reputation on scientifically formulated coatings that perform in real-world conditions — and their undercoating lineup is no exception.
The RAPTOR Undercoating Line
U-Pol's flagship undercoating offering centers on the RAPTOR product family, available in both Rubberized and 1K Tough Undercoating formulas. RAPTOR Tough Undercoating is ideal for protecting underbodies, rocker panels, and wheel wells from stone chips, salt damage, moisture, and rust. What sets these products apart is their versatility and adhesion: RAPTOR Tough Undercoating has excellent adhesion and can be directly applied to properly prepared metal, aluminum, fiberglass, and plastic, and dries to form an attractive, textured finish.
The Rubberized variant brings added flexibility to the formula. RAPTOR Rubberized Undercoating is ideal for protecting underbodies and wheel wells from stone chips, salt spray, moisture, and rust, with a 1K heavy duty formulation that delivers a durable, abrasion-resistant finish — and can also help dampen road noise. This dual-purpose capability — structural protection combined with noise reduction — makes it a go-to for restorers and daily drivers alike.
For those tackling tight spaces or complex geometry, the aerosol format simplifies the application process, allowing for precise and even coverage without the need for specialized equipment. The 1K heavy duty formulation gives a durable, abrasion-resistant finish that acts as a barrier against stone damage and corrosion, and is perfect for covering weld marks and seams — and when used in the engine compartment, can also help with sound dampening.
Gravitex HS Stone Chip Protector
Beyond the RAPTOR line, U-Pol's Gravitex HS is a standout solution for stone chip defense. Gravitex is a durable, tough coating that protects against stone chips, damp, rust, and salt — and this quick-drying chip protector can restore the original stone-chip finish and performance. It can be applied to panels and compartments inside engines to prevent vibration and sound. The high-build formula is especially useful during restoration work: with just one application, it can cover seams and weld marks, thanks to its thick and strong formula.
