It is a state-of-the-art, stand-alone spray sealant that provides real, durable protection for paint, plastic trim, wheels, glass, and all exterior surfaces (except rubber).

Opti-Seal flashes almost immediately to leave a polymer film on the paint. Opti-Seal is not a short-cut product. It is a state-of-the-art, stand-alone spray sealant that provides real, durable protection for paint, plastic trim, and wheels. This is a last step product, not a maintenance product.

Always use a clean and dry applicator to spread Opti-Seal over your vehicle. Prep the paint before applying Opti-Seal. Remove any swirls or imperfections beforehand because Opti-Seal is a true paint sealant with no cleaners or fillers.
