Denver, eh? Interesting. I know a lot of Supra owners out here... never met one female owner... actually not true, are you in your mid 60's, live in Cherry Creek and drive a mint 89+, white turbo? If so, we've never met but I've seen you on the road and the car parked out in front of your house a lot.
3" aluminum molding.... we're not talking about a Supra then. What is this mounting to and is it bare aluminum or painted or powder coated? How did you prep the two surfaces before trying the 3M tape and what type/grade of tape was it? There are many different 3M double stick tapes and a few different automotive tapes.
