Marabu Classic Clearshield Gloss decal protectant

How long has this application been in place? I mean, long enough to tell if it's actually going to work well?

I have new graphics from Keystone for my Fuzion, but I'm afraid if I go through all the work of removing the old and installing the new, they'll just deteriorate like the old ones. If this stuff works it would be worthwhile to put on the new graphics.
