Not knowing what product a detailer was going to use on our last coach i learned it was poly glo. Coach looked awesome for a bit aver a year then some of it started wearing off in wind prone areas. I realized that reapplication is required every year and i wasn't about to spend that much every year. I tried to remove it and was unsuccessful, a real PITA to remove and i just lived with it. That experience with Poly Glo was a major decision point to trade in for a another new to us full body paint coach.
IMO i would NEVER use poly glow or other similar products. I still have some new poly glow products if anyones interested to test.
What i use now to wax the coach is
wash wax all, takes me a bit over an hour to wax the complete 37' coach roof included. It's so easy i do it several times a year.
