For those with exterior decals ....

I've seen wax give decals that "white hazy look" so avoid waxing them.

Wax is better than nothing, but a polymer coating called ReJex is better. Check it out at Www.rejex.com. This will protect your entire RV including decals . I love this stuff.

Try 303 Protectant on your decals.

Any quality automotive wax will do, and no. Wax won't hurt the decals. I use MeQuires cleaner wax, and Turtle Wax.
