I'm fresh to the game, but I've been practicing, reading these forums, and watching youtube tutorials like crazy (Window Tinting Business and Ralph Van Pelt, mostly). I even have training scheduled through 3M in Chicago, but that isn't until February. I understand contamination prevention pretty well. I've even remodeled my bay, sealed the floor, and have a dedicated pressure washer that I use to clean the floor after every car.
My problem is I'm still getting contamination through over-handling the tint on side doors on cars with deep gaskets. This causes finger bubbles, which in turn creates a vacuum which sucks trash out of the gaskets into the film. I've double-snapped preshrunk and two-staged, but I can't tuck the tint into the side gaskets without bending the tint somewhere and creating a vacuum and sucking in trash. I know the answer is likely that I need to pull panels and gaskets, but I just really don't want to do that. I've never worked on cars before this job, and I can foresee headaches.
I've ordered the gasket wizard and will attempt to bottom load when it arrives to reduce install time and over-handling, but in the meantime, can anyone offer a theory of targeting and squeegee pattern? I'd like to not just know WHAT your routine is, but WHY you do it so I can fully understand the mechanics and help develop my own skills. As you may have guessed, I'm an over-thinker, and I'm sick of wasting tint and beating my head against the wall while I trial and error my way through this admittedly steep learning curve.
Appreciate any help, dudes and dudettes!
