Lots of guys don’t permanently install them. They leave them in the trunk and place them on the air cleaner when they lift the hood at car shows. Once you close the hood, they are gonna get scrunched.
And you can have show foam and driver foam; if glued down so much for that plan. I've got some NOS foam that I'll sometimes use at shows.
I used black permatex. That weatherstrip adhesive is really hard to remove. There's a reason they call it "yellow death"
Spray headliner adhesive: A little dab'll do ya! These have been on for 4 years now but I winter park the car with the hood up. These were the good ones with the outside "skin"... ws
