Products include, but are not limited to: detergents, surfactants, acid free degreasers (to break down dirt and soil), detail clay (to remove invisible microembedded surface contaminates), waxes, silicone and non silicone based dressings for plastic trim and tires. Buffing compounds and polishes to resurface and improve reflectivity of the paint finish, as well as a variety of applicators, brushes, and drying towels.
