If you are having trouble with getting your dash cam from falling off your windshield like me, then you’re probably wondering what you can do to make it stay up there more permanently. The answer is to apply an adhesive; the best way to do it is to get a VHB tape. VHB (a.k.a. Very High Bond) tape is a very strong double-sided tape, that will help keep your suction cup stuck to your windshield while holding up the weight of you dash more than adequately. You’ll typically find 3M VHB Tape as the VHB tape is proprietary to 3M.
