Proper care of RV decals . . . Is there such a thing?

For longevity of decals, the best thing you can do to them is to keep them out of the sunlight as much as possible.

I believe this too! My trailer is 13 years old and I wax it twice a year with Meguiars Flagship wax. The right side decals look like new with sharp edges. But the left side, which gets the afternoon sun, are faded and the edges are peeling.
