The RejeX web site specifically states that this product does NOT provide any UV blocking properties. Not sure how good any of them really are at this but I want to do as much as I can to keep my decals from fading so I use a product called Voom. It's easy to use, leaves a nice shine and advertises itself as a UV blocker. I figure if sunscreen can ward off a sunburn then possibly this stuff can do the same for my coach. I do plan to try RejeX on the front (the buggy part)!
Use Turtle Wax car wash soap mixed 50/50 with Megiures car wash soap, TW Wax & Dry, TW Ice, & had had good luck so far. The nice thing about the Wax & Dry is you can do windows, plastic, rubber, everything.
