OK, did the experiment. I took a piece of aluminum (simulating the trim) and a shop towel (simulating your cloth upholstery). I put a 6" long x 1" wide strip of PSA on the aluminum and removed the release liner (paper backing). I applied the shop towel to the PSA and pressed it down. Next, I used a heat gun to heat the towel side of the stack and then rolled it down using a
2" diameter roller. The cloth stuck marginally, in shear it was pretty good and I could lift the aluminum with the towel. However, in peel, the towel pulled away easily. Normally, when we attach a engine controller to a heatsink (G10 to aluminum) the stick is instant and it does not pull apart.
