We have a 2009 Sundance 5th wheel that we bought used. It really shined when we got it, but we cannot get it to shine like that any more. What is recommened to wash and wax the exterior to make it really shine? We have used different wash and wax combows, it cleans it but does not really make it shine. If we wax it, can I used a wobble buffer on it, (it's not a high speed buffer) I really don't want to get up on a ladder and wax it, my wife fell off the ladder washing it and broke her wrist last year. Any help would be great. Thank for your time.
