You might try 3M 77 spray adhesive. Hold the nozzle close to the seam, spray, wait a few minutes for the adhesive to begin to set then apply tape. You can wipe any overspray off before putting the tape on. Forget what I used now that I'm trying to tell you. Sigh.
I cut my tape before spraying adhesive so I had the strip ready to apply. Really clean and well rinsed surface is important. Never thought to try alcohol, that shoud dry fast and leave no residue.

seam tape is low compared to other companies that sell same product. Thinking is the stick-em is where the money is saved.
