We did the Zep High gloss floor finish. Based on our experience and not what we have heard, the tired exterior of our 1999 looks new. Scrubbed the entire exterior with barkeepers Friend, wash everything down with TSP and applied 5 coats of Zep. The description we get from everyone that sees it is one word. Wow. I did the coach in sections, first the front, then the rear and eventually each side. Just to take the process easy. After a few months and lots of rain and travel it still looks great. It was a complete transformation. We're in Florida. Chuck
