i had introduced air and lots of it using my heat gun trying to simulate the worst case scenario... 180v2 with lamination creased ever so slightly and 180v3 with lami. on the same panel with same amount of heat dispensed the air faster and smoothed out without creasing. also both lifted well after touch tacking. the primer offered by 3m also benefits in adhesion issues.
I only used a sample roll of the v2 and it appeared to only have channels running in one direction. I intentionally introduced some bubbles so that I could see how it reacted, and it was my impression that the channels were indeed only in one direction.
