Supernatural Gloss Trim sealant coats smooth and textured plastic surfaces in a layer of ultra-durable crystal resin around 50x thicker than a coat of wax or sealant. The result is a long-lasting, semi-permanent finish that can enhance the appearance of exterior trim, whatever the colour.
Note that this product is challenging to apply, due to being of a varnish-like nature, and it may not give a consistent finish to heavily faded trim. On more modern vehicles, though, it poses no such problems and careful application can reward with spectactular results. This 50ml bottle (enough to do 1-2 cars that have a normal amount of plastic trim) comes in a kit with a lint-free application cloth and full instructions.
Supernatural Gloss has a shiny finish; use the Supernatural Satin Trim Sealant if you prefer more of a ‘natural’ look.
