Double-Sided Tape: Which Type/Brand is Best for Long-Term Holding Power?

You can just add pieces as needed. When I did my last ALP install, I used the brackets, problem with tape is that it very hard to make the needed small adjustment after you get them installed. Alignment is very important. I recheck my all the time and can make the needed adjustments. They will move with time.

On front, mine are mounted in the grille mesh on a 2013 Dodge Charger SRT8.

I Dremeled out holes slightly larger than the ALP heads. I stuck them in the holes with the double-sided tape that came with the ALP. That held it "about right" while I did fine adjustment to level and pumped some hot glue in the crevasses.

It has survived many automatic car washes.

I use the 3M VHB its black not the regular 3M grey kind. I cleaned my surface with alcohol wipes first, then with the VHB tape already applied to the brackets I use a heat gun to heat the tape up until it kinda has a shine to it and slap it on there. Let it sit for about 2 hours in the shade, then I snapped my heads into place. This is the way my local ALP installer did it. But the 100+ degree weather and small mounting surface made them fall of earlier this summer. So instead of driving a hour back to have them reinstalled I just purchased the tape they used and DIY.
