I have recently been on a course on 3Ms new 480 material.
To say this material will change the game is an understatement.
It is a totally memory free material which when formed onto a surface does not return to its original shape.
3M will not tell you what PVC free properties it holds and it seems to be a very very closely guarded secret as to what the material really is!!
We have wrapped 6 vehicles in this material with no issues at all.
Supposedly the issues with stretch marks and spots are a profile issue, this is what we were told.
As a fore note to this 3M are to discontinue their 380 range of cast wraps very soon so we will all have to get used too this material.
