At the end of the day, 3M is just another company like yours and mine..and the bottom line is, you (and I) can't do anything about it. They can run it how they want...and if you (or I) don't like it, we can choose to move to a company who SUPPORTS it's customers, rather than bankrupts them. That's the freedom of choice. Support the companies who support you, and I know WE won't be considering switching to 3M because we have a great relationship, great support (on film and even diagnosing profile/printing issues sometimes) and about 50 shops to buy Oracal film from locally instead of just one or two.
That's all I will leave in this thread....if you guys have THAT much of a problem with 3M, stop buying their film and move to an equally as great product. That's all there is to it - it's that simple.
If your customers have a problem with you not using 3M film, well, when was the last time they looked at the backside of the liner on their printed wrap before it was installed?
