There is not much stronger than this 3M tape, the slightly thicker tape may hold better but I’ve used it professionally and personally for several years, I’ve seen it hold 15 pound radios stuck to the roof of a yacht with no problems five years later. The real key is how you prep the surface. Lots of alcohol, or acetone, once you pull the tape, let it cure for a minute before you stick it on, make sure you’re using enough…So if you were going to try and attach something that was the size of a baseball/ credit card, it would be tape around the whole edge and 2-3 long strips down the middle…Any areas that are slightly still away from the surface, would require a few pieces of tape stacked on each other.
