Polyvance's Bumper & Cladding Color Coat is an advanced, low-VOC, solvent-based coating designed to permanently recolor molded-in-color, textured TPO and polypropylene plastic bumpers, side cladding, and trim found on many of today's cars, trucks, and SUVs. Bumper & Cladding Coat requires no adhesion promoter or sanding to apply; simply clean and spray! Bumper & Cladding Color Coat is not recommended over other substrates such as raw polyurethane (PUR) or OEM primed bumpers without sanding. Bumper & Cladding Color Coat permanently recolors faded, marred, and stained plastic. It's not a silicone-based product that puts a temporary, quickly-fading shine on the plastic. It's an advanced solvent-based coating that sticks to the surface like glue, permanently recoloring it.
