Bumper & cladding coat adhesion primer is an advanced, low-VOC, solvent-based, non-sandable primer that is designed to stick to "problem plastics" like TEO, TPO and PP without sanding or pretreatment. The low VOC formula, sprays smoother and has improved topcoat compatibility over the original formula, plus there is no close on the window for topcoating. The low VOCs mean it's legal in all 50 states and Canada. (2.09 lb/gal VOC). Bumper & cladding adhesion primer is designed to permanently stick to the bumpers, side cladding and trim found on many of today's cars, trucks and SUV's. As everyone knows, most bumpers are made from plastics that are very difficult to get anything to stick to. Bumper & cladding adhesion primer will stick to raw TPO and polypropylene. Once the primer is on, your basecoat-clearcoat will stick. Bumper & cladding coat primer may be topcoated with most solvent, waterborne base/clear topcoat and single stage systems without sanding.
