Not for guns, but for autos. My 2008 car and truck have lived outside their entire lives, and the black plastic trim has suffered accordingly in the NC sun. While a number of specialty treatments restore the nice shine, the durability is only on the order of a couple of weeks max. Cerakote offers wet cloths containing a ceramic compound, and since ceramic polish has performed great on the paint I gave the Cerakote a try. It still looks great after a couple of months, clearly more durable than the cheaper options. If you like purdy black plastic trim, give it a try.
