I just keep mine well waxed with Nufinish wax, because if you store it in an outdoor RV storage lot, and there is dust flying around, and if there is wind, it will get up under the cover and rub your paint job down. So I decided to wax it with Nufinish twice a year, and it looks brand new. I was like you until I saw where i was going to store it, and there is lots of wind and dust, and did not want to take any chances. Plus it seemed dangerous to be up there trying to handle a big Ol' cover to cover our 42' long fifth wheel!
