The success or failure to the Red Max application is the preparation before application. It has to be WAX FrEE and well rinsed before you apply the RMP. I had great results on my 01 Fleetwood. Lasted just over 3 years before the drivers side (normally parked with that facing some hot sun) started to flake. A simple process to use the RMP remover took about 2 hours and I reapplied. The passenger side still looked great, but I gave it one coat and it refreshed the entire MH. Preparation, preparation, preparation.....BTW: We do fulltime.
