Ok so heres an honest review. Today I got to use Arlon panels on a trailer immediately after using 3m on the same type of trailer.
Air Release: 3m gets this one. I felt the air moves through the 3m channels better, maybe because the Arlon is more aggressive, not really sure, but overall 3m gets this.
Repositions: I felt no difference at all in the 6000XRP vs the 3m. Even steven here.
Durably: I found the Arlon a little more sensitive, and wanting to wrinkle a bit easier. Problem solved by using a little more heat the 3m.
Other: The Arlon seemed much much more sensitive to heat then 3m. I found 150-200 degrees on rivets for the Arlon was to much.
Overall: Both are great. I think with a little getting used to. I could wrap with the Arlon just as easy as the 3m. 3m just is easier from a installation standpoint. Your definitely getting what you pay for here. For the price break Arlon is just awesome though.
There you have it, an honest review from an honest person who just used both brands back to back on the same surfaces, same shop temp, same day, same hour, both 2mil cast films, laminated.
