So a fellow tinter recommended this new thing called soak shield B/C I do a lot of windshields on high end cars. I got online and checked it out! It's basically high absorbing microfiber towels that have been made into different sized ropes. You stuff them down the gap between the dash and glass to get all the water that you can't get to because it would be in the way of you laying the film
looks awesome- mine should be in tomorrow, I'll let u guys know the results of using soak shield as soon as I try it!
