weird problem on camaro back glass

[Taco_Conch]

I've noticed tint likes to stick really fast to the defrost lines on the new camaros. When checking my work, I'll sometimes notice a little excess water bubble. When I try to either push it out the side or down through the bottom, a defrost line will block it and it will shift elsewhere. I think making second passes with my squeegee and bulldozer is what's causing these water bubbles to sometimes pop up. The camaros's the only car I have this problem with. Any suggestions? Thanks dudes.

you can avoid this by shrinking the back window evenly. Pucks develop when you don't. Some cars have thick defroster lines that causes pucks to pop up easier. But a even shrink job prevents pucks from popping up. good luck

Thanks dude, but they're not puckers. Just excess water bubbles I want to get rid of so everything lays evenly when the tint cures. The bubbles aren't white and not on the lines. Rather trapped between them. The tint sticks so well to the lines that it's difficult to push water past them.

Get as much out as possible, explain to the customer it may take a little longer to dry. It'll dry out, as I'm sure you know.
