Help - Problem using weatherstrip adhesive with Universal Clear.

Bummer.

The regular yellow weatherstrip adhesive (Dynatex brand) attacked and lifted the Universal Clear on my door. The clear was shot 10 days before I installed the weatherstrip and my shop has not ever dropped below 60 at night.

Anybody else run into this?

What glue should I use for this instead? I've always used this stuff in the past and never had a problem like this.

At least I hadn't done the passenger door yet.

I guess to fix this I'm going to need to remove the weatherstrip and sand and reshoot the inner part of the door. Unless someone has a better idea.
 
I haven't seen that happen before, but we use the 3M black w/s adhesive. I didn't think they were different except for the color, though.
 
I also use the 3m and have never seen this issue before either. No idea what the differences would be.
 
Ouch... Never had any problems with 3m Black or Yellow, never tried the Dynatex stuff and never will! There must be some fairly strong solvent in there. The TDS shows acetone and tolulene.
 
I don't have an answer but am curious if that happened all the way around or just that section. In the past, have you used the universal and this product?
 
No, this is the first time for this particular brand. And also no, this is the first time I've used UC.

The other thing is that since these seals have pins every 3 or 4 inches apart, I didn't wait for the glue to dry very long before I mated the rubber to the door as I didn't need it to stick to hold the rubber in place. This could have added to the problem.

The section I took the picture of was the worst area and is the only section where it lifted bad enough to need to be repainted. I might have not given this area as much time to dry as the rest of the door.

This problem could be a combination of the way I did it plus the glue having stronger solvents in it than the 3M. Or maybe all from the way I did it. I don't know.

I'll buy the 3M black and next time use it differently. I'll apply it to the rubber first and let it dry completely. Then I'll apply it very thin to the door, let it get tacky and then mate them.
 
Sooo sorry to see that.. Have you called Barry and ask his opinion on the situation? If you have, what was his repsonse?? We need to share so someone else does not run into this problem
 
No, I haven't called since this happened yesterday. Don't know if he monitors this board on the weekends. I'd like to see him address this here in case someone else has questions. Maybe I'll pm him if he doesn't reply here by tomorrow. I think threads like this are good to have so someone doesn't repeat my mistake.

I'm really thinking this happened because I didn't let it dry before mating the rubber to the door. Normally I would do that but as I said, I didn't since I had the pins to hold it in place. Doing this allowed the solvents in the adhesive to work on the clear for longer. However, this tube of adhesive was new and a brand I haven't used before. It seemed no different working with it than the 3M I've used. (That is until discovering the lifting the next day.)

Anybody ever used 3M and not let it dry before?
 
Now not sure how the process was done but perhaps Roger will call me Monday and we can go through it.

In every case I have seen this happen over the years to a few products, there has been one common denominator, the paint was fresh (not cured) and the main thing was the metal was cold at the time the glue was applied and you must remember the rubber strip is hindering the solvent from escaping from the glue and they are setting there on fresh paint and with cold metal will work just like a paint stripper.
 
Roger looks like we posted the same time, I never let mine dry, usually have 3m or Transtar type glue.

I should add, that something like this is pretty rare Roger but does happen, those kind of odds, it would have been a good day to buy a lottery ticket.

One of those things, there really is not an answer for and usually out of our control.
 
Thanks for responding Barry.

My shop was 70 degrees and like I said before it never got below 60 at night since I put the clear on 10 days ago. So, I don't think it was a temperature or cure issue.

Something I didn't mention yet and may have also been a factor. This rubber has a U shaped groove down the center of it almost one eighth of an inch deep. This fills with adhesive when spreading it on. Add that to the fact that I didn't give it good dry time and I think there was a lot of solvent trapped in there that had time to attack the clear.

I'm going to get some 3M and give it more dry time and hopefully I'll never experience this again.
 
You won't have a problem with 3M. But there are some adhesives out there that are designed to bite into paint- 3M's emblem adhesive is one.
 
Just a follow up here. I bought the 3M black and did the other door. I used it exactly as the directions said. No problems at all.

It was obvious to me that the solvents in the 3M don't attack the clear. The solvents in the Dynatex do.

Moral:
Don't use Dynatex weatherstrip adhesive.
