I bought this:

I really liked it on the test. It's easier for me to use than the 3M. While the 3M tends to dry to be very brittle & hard this stuff is a bit more gooey? While that might scare some folks away I don't think it should.
What I mean is this........after doings tests with each and waiting overnight I then went back and peeled each up a bit to see how strong the hold was and what it looked like.
The 3M held well but when peeled came off and the edges seemed to be a liability. As the tolex was coming up you could see the glue peeling back but most of it was hardened up and not offering much resistance. The 3M also tacked up super fast and once the tolex was put down it was on and not moving at all.
On the tolex glue it held great all the way to the edges, came off w/ a bit more tugging than the 3M but also had huge what I will call "legs" or strands of glue between the tolex & wood. It really wanted to hold on to it even as I was pulling it off. All in all, definitely behaved a lot more like the original glue I had taken off and seemed to seep into the nooks & crannies of the wood & tolex a bit more. It also took quite a bit longer to tack up which was good as it gave you enough time to work out the bubbles and pull it off and re-align if needed.
I am moving forward w/ the tubesand more tolex glue. I did the back panel and it came out great. Only issue was on a couple of the edges I didn't massage it into place quite enough to get a strong bond and didn't catch it till too late. That's just user error and won't be visible at all anyways. Glad I learned on that piece so I can do a better job on the rest of the cab this week.
