CS Hyde 3M 4941 Very High Bond Conformable Acrylic Foam Tape, Double-Sided VHB Acrylic Adhesive, Liner, 45mm Thick, Dark Grey, 0.5" Width, 5 Yard Roll

I use 3M VHB gray 4941. This is what I bought. I put it on the mount and let it cure for a day, then I stuck the mount onto the rear view mirror cover and let that sit for a day. Then I mounted my Comma.
