The VHB tape only works well enough to do basic skin bonding. You'll run into parts like this that need to be glued together.
So I superglue it and then clamp for 20 minutes and move section to section until its all locked together.
This is what it looks like 15 minutes later after superglue. I so far used 3 bottles of this stuff on my droid so far.
Spot gluing various sections that need it. Then moving on to putting some JB weld on the some of the seems.
