Decals Starting to look Shabby

I was in the vinyl sign business for a number of years, and I can tell you the reason for these problems is that the RV industry uses cheap vinyl for its graphics. Like almost everything else it is about saying a buck. Done right with quality vinyl graphics can last for 15+ years and still look good. I know of one sign I made 22 years ago that is still up and still looks ok, if not great. It used 2 different grades of vinyl, one was fancy sparkly blue vinyl with ultra aggressive adhesive that was a pain to work with, but still looks good, the rest was in a premium green vinyl, which has started to fail over the last few years.
