A buddy of mine, who worked for Jaguar for several years, hooked me up with a bottle of wax the other day. It's called Collinite's insulator wax #845. It is the single most incredible wax I've ever used. It's made for high tension power line insulators, but it's clear coat safe. I found it online with a simple search, so it's available for online ordering. Went on really easy, buffed out by hand. The finish is incredible. The past few days of extremely hard rain didn't seem to faze it at all. It's the first wax that I've ever been really impressed with.
