I'm always amazed when I'm removing old door and trunk rubber at how hard it is to take off, most of the time. In my latest '54 Kaiser project, I'm using a putty knife and a lot of tugging. Would leave it on, but after 60+ years it's lost a lot of it's give and I want to paint. I've never found an effective replacement for adhesion that's at least as good as the old... and I follow 3M's instructions when I use their stuff. Has anyone found something better? Thanks!
3M is always worked for me, just make sure that both surfaces you're gluing are dry before you put them together. Works like rubber cement on steroids !
I'm with Dino64 on all counts - never had any issues with the black 3M trim adhesive stuff if prepped perfectly . Never really had the need to go any further . Damn , that really wasn't any help for ya ... at least you got a "bump" , lol !
Take a heat gun to it. I bet it'll come off a lot easier. Don't get me wrong, I like a little tuggin but just a little.
I use 3M 08011 black. Their older yellow stuff (aka gorilla snot) worked well too. Most of the old gaskets on my Ford were fossilized... needed little help to take off.
In the factory 64 to 70's we had a pot of black sealer. It was called 621 sealer. It was in pots under pressure are in a can that you could pump it out along the rubber. Local GM plant that was all that we used.
Clean the rubber with acetone or lacquer thinner first like said above to clean the mold release from the rubber. Then do the same to the body where you want to stick it.
