I also have used the Red Max floor polish last March on our 2002 Ambassador. It still has a high polish shine after nine months and cleans very easily. I prepped the surface using Bar Keepers Friend liquid paste and a buffer applicator, washed it off and once dry applied the Red Max with a high quality microfiber towel. Three coats was enough to produce an outstanding shine. It will run if too much is applied and it's a bear to remove them. I applied to all surfaces including door and window frames, awning covers and mirror arms and housings. I did not apply to rubber window gaskets or glass. It does not seem to damage vinyl moldings or decals. I did my whole coach in one weekend including the prep and all coatings. I set up a scaffold one side at a time to do the upper half and the lower half from the ground. I am extremely happy with the results.
