Thanks for the suggestion, Jaime. I researched VHB tapes, and learned that there are several types of VHB tapes out there. So, I decided to call up 3M directly. First I was referred to their Automotive Aftermarket Division, and the person I talked to offered a suggestion after consulting with one of their engineers. However, it was not VHB, and looks like it won't hold up to the potentially high temperature exposure on windshields. He acknowledge that VHB is much stronger, so, he gave me the VHB group's phone number, 800-362-3550.
I explained this particular application to the technical support person, and he recommend Product No. 4941, which is "comformable". It also has very good temperature tolerance. I actually ordered from Amazon Product No. 5952, same configuration as 4941 which is gray, 1" wide, 0.045" thick, 3 yards long, but in BLACK. Amazon is an authorized 3M dealer according to the first tech support person, so you can be sure that they're not fake. I need black for other projects that I have in mind.
Here's a link to a the 3M VHB Tapes Design Guide. Just be careful with the color that's listed. For instance, the one I ordered, 5952, is listed as dark gray. The tech person said it's actually black, and the Amazon specs also say black.
