I don't know if it is different now but about 5 years ago I did my rig and helped do 3 others 2 in Durabak one in Herculiner and one in the Duplicolor stuff. After about 2 years they all looked really chalky on the outside, coulnd't get them to shine up at all. The only rig that is still around is white Herculiner and it looks like crap. Don't get me wrong the stuff is still doing its job hasn't peeled or cracked it just looks really bad. The truck that was done in Durabak looked like this when the guy trashed it about a year ago, wasn't black anymore, more of a chalky gray. None of the uv protector stuff that they sell now was around then
