Mallard's right on.
Our Crystal Coat is a clear acrylic lacquer that was developed specifically to bring UV protection and a glossier finish to those looking for these two features.
Won't yellow, "spider crack" and will hold up to many years of sun exposure. Great also for resurrecting an old sun faded coating (of any kind) AND for keeping those chrome or alloy rims looking factory new.
Info available on our website.
