Mounting tape for JDM wind/rainguards

Anybody know of one that is stronger than the other? I'm putting on my nerdy-cool JDM wind/rainguards on my BG6 and they attach with 2 clips that don't hold much force at all, 2 bolts in the doorjambs, and 1/2" tape, full-length, to fix it to the car and seal against rain and wind. I didn't find much choice at the Kragen, I'm off to the Auto Zone to see if they have anything there, but since we cook in the summer and freeze in the winter, I want a good quality 3M or something similar. Any recommendations?

Here's the guards on a JDM BG5. (I scored the JDM projector headlights, too. They work great, but I still need to fidgit with them a bit and adjust them....not as bright as I'd hoped, but better than before)

Thanks.

I would use the 3M Automotive Gray Acrylic Foam Double-Sided tape from Levine;
