HAven't tried the Solvex, but have tried the Gamut. I'm not positive but I'm pretty sure it's rebranded Avery MPI1005EZRS, it looks, smells, prints, and installed exactly the same. We used it on a few vans, not full wraps, actually just printed/cut stuff mostly. Both vans had to be redone within a month. Fellers claimed we didn't post-heat it enough, but we heated it as much as possible before it started bubbling/burning. If it is rebranded Avery, I guess that's the problem right there.
I have used Solvex's regular non-AE CarWrap film and for a regular cast film it always worked great. I'd assume the AE stuff is as good.
