Hi, I used the automotive version. I cut that precision weatherstrip into short pieces, and did some tests gluing them to a painted license plate. I tried permatex, 3M, and goop. Clamped them down, let sit overnight, the goop was the winner. It could be something in the rubber weatherstrip itself, like silicone or something that did not adhere to the 3M. Or, my tube of 3M was old....but the 3M super weatherstrip adhesive sure adhered to the paint good, I mean really really good, but absolutely did not stick to the rubber. I should have known, the same thing happened to me 6 months earlier when I glued an aftermarket door weatherstrip seal to a 57 ford pickup door I was working on. It fell off the next morning 😆.

Did you clean the bonding surface of the weatherstrip samples with alcohol (or similar) before applying the adhesive?

I really like this stuff for all adhesive needs:
1 Gal. DAP Weldwood HHR Contact Cement You may have to clean some weatherstrip of its "mold release" before trying to glue it in. A little lacquer thinner on a rag and a few wipes on the surface to be glued is all that is needed. For door weather strips, I use an acid brush, start in the sharp corner at the top, back of the door. You can do it in sections about 18 inches long. Just apply adhesive to both surfaces, wait about 3 minutes, and then press and stick. It is going nowhere after that.

Thanks, Parman. I will be heading out to Menards to get the automotive Goop tube. I don't know what 3M was thinking designing a glue which is black. Clear one makes perfect sense.

I did clean it! First with alcohol, then the 2nd attempt I even roughed up the surface of the weatherstrip with sandpaper, then cleaned it. I even bought another small tube of the 3M super weatherstrip adhesive from Walmart and got the same results. The fact that the adhesive adhered to the paint so good, made me think that it was still good. The hatch weatherstrip I got from Australia had a totally different feel to it. The rubber was more "sticky". It required 100% talc powder to be applied to it after it was glued on, so the painted hatch surface would slide over it when you closed the hatch, until the seal bedded in.

I agree, that's what I used on all the vinyl and firewall pads. I don't know why I didn't use it on the weatherstrip......I was amazed after 50 years, it just peeled right up and didn't harm the vinyl in any way, still pliable.
