3M VHB Tape 5952, 2 in width x 5 yd length (1 Roll)

Used this alongside adhesion promotors. My spoiler is NOT going anywhere!!

This tape is amazing!! Used it to put on new truck bed rails, and the adhesion is awesome.

If you need a good double-sided tape that's removable, DON'T BUY this! If, on the other hand, you need double-sided tape to stick two things together for good, this is the stuff you need. OK, I suppose you could pry this apart if you really needed to, but you are going to have your work cut out for you. This is seriously sticky double-sided tape meant for industrial applications. I've used it to stick plastic to aluminum, rubber to steel plate, fiberglass to metal, etc. One repair was for a tractor fiberglass panel, one for an outside sign and one for a metal plate I use as a portable anvil that needs a rubber backing to absorb hammer blows. In all cases, this stuff has lasted years with no separation, no slippage, no nothing other than doing the job it was intended to do. My only negative is that once the exposed side is stuck, it's tricky to peel off the protective red separation layer from the other side. But that's a one-time challenge for a lifetime of intended use.

Extremely strong and reliable! Holds everything from car accessories to household items with ease. Far better than standard double-sided tape.

Works great. Definitely sticky. Has worked great through cold weather and rain so far.
