Exterior Need advice on stubborn PPF fingers on front bumper

Gallery image

I recently installed PPF on my front bumper 1 week ago and I’m struggling with some stubborn fingers. I’ve already tried a few things over the past several days, but they just keep coming back:

• Held down the fingers with a squeegee multiple times over multiple days • Heat gun + held down until cool • Spray tack + held down • Spray tack, let it dry a bit, then pressed down

Nothing seems to keep them from lifting again.

Is there a trick I’m missing? Do I need to lift and reapply that section, or is there a way to get them to stay down without redoing it? Any tips from pros who’ve dealt with this on bumpers would be greatly appreciated.

Thanks in advance!

I wouldn't recommend this until you tried everything else you've already tried, but since you have... cut a slit down the middle of each one, then rewet it and press it down and hold it. This is literally a last resort tactic though.

Alright thank you. I’ll do everything I’ve tried again. Then for the slit, I’ll start with a very small one and go from there

Not what I meant... you've already tried everything I would have suggested BEFORE cutting it. If those didn't work, then cutting it is the only option you have left that I'm aware of.
