The trailer did, not me. I got the decals removed. It looks 100% better. There is some "ghosting" where the skin under the decals hasn't faded, but even that looks better than cracked, peeling decals. I think that with some good polishing, the "ghosts" can be blended to become much less noticeable. I am going to replaced the Fun Finder X decals on the sides and rear. They won't be in the factory style, but they will look good. I'm also gong to replace the decal on the front window shield. It was missing when I bought the trailer. I washed the whole trailer by hand, using a bleach based cleaner (washed it w/soap & water the other day), and all the mold/mildew spots are gone.
