    Weather strip adhesives.

    Over the weekend I went to install a new weather seal for the hard top. I went and grabbed a tube of the 3M weather seal adhesive.
    Applied it to the topper and to the weather strip. Let them dry to tacky as per the instructions. Installed the seal and clamped it up. Went out today to to remove the clamps. Rolled back the edge of the seal and the adhesive just peeled right off the seal.
    Just to rule out the weather and colder temperatures, I applied some more adhesive to a small peice of the weather strip I had trimmed off. I let it set up for a about 3 or 4 hours. And sure enough I can peel it right off.
    Any advice or recommendations would be greatly appreciated. Looking to get the hard top back on. Has anyone used any other products?

    Odd.. I've used the same 3m adhesive but got it from LMC when I ordered all my seals (doors, cap, and tail gate) and have had no issues. Did figure out it sets a bit quicker than what was on the label, could have been the humidity though at the time. I did scuff the pinch welds/seams with a red scuff pad prior to applying but not sure if that was a factor or not.

    Sorry if I steered you wrong. It worked fine for us doing the exact same weather stripping. It makes no sense it would peel off the weather stripping. Wonder if you got some bad product from 3M.

    If I were you, I'd wipe some of your cut up left overs with acetone to test just to make sure it doesn't have any manufacturing residue and try again. If it still isn't working, then it has to be some bad sealant.
    We're working on it...

    Not your fault at all buddy. Nothing to apologize for. I've been thinking the same thing. Prob a bad tube or something. I just scrubbed a test peice with paint thinner and applied some more. I'll check it in the morning to see if I can peel it off. If it doesn't work then I'll be taking it back to oreillys or contacting 3M about it. The stuff on the topper I can't even scrape off. That stuff is on there.

    My bet is cold temperature...I laid down some caulk on the hunting hut door threshold Sunday before last. Went back out there on Wednesday it wasn't cured. This past Saturday it was cured after we warmed up above 60°F for a day.

    This happened to me before but it was due to that powdery stuff on the seal. So i had to wash it and it worked after that. But since you cleaned it and it still didn't work...I think you got a bad tube.
