This is the thread from
Fiberglassrv.com that was posted by Randy Bishop (referred
here in March by Replant). On this page, Bishop says he had the finish on two trailers for almost a year with no yellowing or peeling. I read the whole thread before I decided the risk was minimal.
Red Max does have a stripper so a peeling, yellowing finish could just be removed completely. I also read that strong detergent like tire cleaners will remove it. It has saved me from rewaxing for the last couple of months and looks to have a life span of at least a year. Out here in the Arizona sun, it would yellow if it was going to anywhere.
The advice I have read is to recoat once after a year. At some point it seems I would want to strip it off and start again, to avoid the dreaded "wax buildup" like in the corners of waxed floors. That might happen with too many coats of RMP too.
It is funny, the fiberglassrv site asks for before and after photos too. The difference is just that impressive.
