Urethane Supply Company’s Bumper & Cladding Coat adhesion primer is now available in white in addition to the light and dark gray colors already available. Virtually any basecoat requirement can be met by adjusting gray Bumper & Cladding Coat Primer with white. This solvent-based coating makes automotive base-clear topcoat systems stick to unprimed TPO and polypropylene plastic bumpers without sanding. Once dry, you can topcoat it without sanding or scuffing, saving several steps. It’s compatible with most urethane, polyester and many water-based base-clear topcoat systems.
