Last year my parents had their motorhome detailed by a reputable (at the time) mobile detailer. When he waxed the front of the motorhome, the wax would not come off. He claims the paint soaked it in and would return once he found out how to get it off. Personally, I think he burned it. Now, I have started my own mobile detailing and am still fairly new at it. Keep in mind this was last summer. Yesterday, I tried washing it, drying it, going over it with a clay bar, and my Porter Cable DA polisher with swirl remover and polish. No luck! Any recommendations? I would post pics but it is dark here. I was thinking maybe trying acetone? Im at a loss on this one, Ive never run across this
