Check auto parts stores, specifically ones that also sell refinishing supplies and paint. A very similar product is also available from hobby shops, and is sold as 'servo tape'. This is very commonly used to adhere trim and accessories to vehicles; in a former life I was a mechanic at a 4WD shop that also sold truck accessories. We used this to attach those plastic bug deflectors you see on truck hoods, and never had any issues. The main thing is, the surfaces need to be EXTREMELY clean. Wipe down with IPA, let dry, then wipe down again with a fresh cloth and more IPA. I'm also calling BS on alcohol removing this stuff, I have tried that unsuccessfully. I did have luck with goo-gone and a scotchbrite pad, but that was very difficult and time consuming. This is a permanent adhesive.
