I'm going to have to disagree with you on this one. I just wrapped my buddy's G sedan in vvivid's matte copper and it worked great and went on pretty easy and hasn't peeled anywhere in 3 months. Plus the 5 year warranty and their decent customer service is really nice. If I buy from metro and there's an issue with the film they could care less.
I will say that getting the newer films from them is mandatory, since the old films with old style adhesive don't conform very well at all and have garbage air release.
Thinking about it now, I'd still put them underneath the big brands since their films definitely discolor much easier than normal, at least in my limited experience.
All in all I think it's still a viable option if you're on a budget, but looking at it all in hindsight that G was decently more difficult to wrap where it probably wouldn't have been if I used avery.
I just went from 90% support to about 50% in the course of typing this. Its a decent film but the weird pliability and ease in discolorating are a tradeoff for having a nice warranty.

 

@Con how would you be able to tell if that vinyl is good to use or not before applying it? Since Alb's vinyl is two years old, would the film start not sticking to the backing paper if it's spent? I'm curious as to how a professional would tell
