Butyl sealant.
When the doors are closed, the gasket is under compression, so unless it is severely comprised, it shouldn't be a problem. That's better than trying to scrape off decades old sealer.along the same lines, is there supposed to be an adhesive holding the strip that goes along the bottom of the windows that are on the doors? i can just pop mine off and it doesnt seem right....
I would think so. If you get a replacement, get OEM. I had aftermarket weather strips on the wifes old ZR2 Blazer and you had to get a running start at the door to get it closed,right on, mine is so loose i can just pull it off with ease. maybe i will try a junk yard piece.
lots of wind noise on the one door too. i occasionally see it bouncing a bit while driving.
do you know if a blazer one would be the same?
