Avery's business practices aside, I will say we have many wraps on 1005EZ that have been out for 5-6 years and they still look like new. Comparing Avery to 3M, they are very similar in application, I like Avery's air egress better, personally, and I like the level of initial grab a little better than 3M (but they're really close there). All in all Avery seems to be noticeably more forgiving during installation than anything else I've tried.
We've also got a lot of jobs out on Oracal 3951RA, which also look as good as new. This would be my top choice were it not for the fact that the initial tack is like super glue which makes it very tricky to work with if your install bay is anything warmer than a meat locker. It is not as conformable as Avery though (in my experience anyway), so it wouldn't be at the top of my list for something like an HHR or Sprinter.
Come to think of it, the only wrap failures (not really failures, but lifting or tunneling here and there) we've ever experienced were with 180C. Properly applied, primered and post heated, we have always had random unpredictable issues with deep channels and creases with 180C. Not every time, not extremely common, but I can comfortably say it was installed properly and I can wrap the same vehicle with Oracal or Avery and almost guarantee the issues won't be there.
Bottom line is, no vinyl is perfect, and none are bad. Avery's business practices of the not-so-distant past are certainly nothing to write home about, but frankly neither is 3M's recent foray into the retail wrap business. All of these companies look out for their own bottom lines before yours. I used to be one of the people who would boycott this or that because of the company but anymore, they all suck and they all will screw you if they get the chance, so boycotting them will leave me without material to work with. So personally, I just use the best material for the job and don't look back.
