No, there is not. It all has to do with sun/uv exposure. Have you ever wondered why the OEM decals on your car and truck last forever and the decals on your camper fades, curls up and looks bad after only a few years. cheap inexpensive decals used by RV manufacturers. I am on my 7th fifth wheel/travel trailer (which will be my last). Any one of my previous campers which I kept for any length of time had decal problems. On my latest camper (which I plan on keeping for eternity) I keep covered. I also only use Aerospace 303 on the decals and wax the rest. I have seen a new product on the market called Graphix Wax, does anyone here have any experience with it?
