Vic,
We have used some of the lessor brands in wrapping vehicles and have never been satisfied with one aspect or another of the films, needless to say we always find ourselves back using 3M film and over laminate.
Regardless of what a sales person tells you when it comes to wrapping cars the price difference between the best and a lessor brand isn't really even a factor....unless your not the one applying it! LOL!
Hope this helps.
