Enhance Adhesion Across Materials

U-POL GRIP#4 Universal Adhesion Promoter is a versatile spray designed to improve paint adhesion on a wide range of automotive substrates — plastics, aluminum, galvanized metal, zinc, painted surfaces, fiberglass, and body fillers. The advanced formula is engineered to reduce surface preparation time by eliminating sanding in many scenarios, helping you refinish efficiently in hard-to-abrade areas like under hoods and deck lids.

Consistent, Smooth Application

Sprays flat for a smooth, even coating that wets out evenly before you topcoat. It is compatible with most water- and solvent-based paint systems, allowing you to pair GRIP#4 with your preferred refinishing workflow.

Protective Barrier for Longevity

Beyond adhesion, GRIP#4 creates a durable barrier that helps resist lifting and solvent attack, contributing to longer-lasting color and finish without adding extra steps. This protective layer supports the integrity of your paint job over time.
