I have read most of the previous posts related to this topic, but still wonder what I should be using on our painted 2003 U295. Over the past year I used Wash Wax ALL on our coach and it seems to have worked very well. In 2011 I washed the coach with water and soap once while living in it full time. For the most part it looked clean with very little effort. But should I give it a good coat of wax or sealer once per year in addition to the monthly use of Wash Wax ALL? Thanks in advance for your advice!
