U-POL GRIP#4 is a ready-to-use, transparent adhesion promoter for paints, adhesives and sealants. It is formulated to improve adhesion across a wide range of automotive substrates, making it ideal for vehicle panels, parts and accessories.
The aerosol sprays flat and normally requires no sanding after application. It is particularly useful in awkward areas that are difficult to abrade, such as beneath bonnets and around boot-lid recesses. GRIP#4 can be overcoated with compatible waterborne or solvent-based paint systems and provides a protective barrier against lifting and solvent attack.
