Without a doub tthe best stuff I have found to date is Scotch 3M VHB tape. I have a buddy who works at a tape company and he brings me the scraps. That means rolls of 50' or so... I have no idea where to get it but...
the stuff is a plastic tape- not foam so it can be taken off in one piece with No residue if you want to move your stuff. I put on a Super Chicken onto my clod and was able to pick up the entire truck, including 8 cell battery pack by the ESC!
Scary strong. But stick a screw driver under it and you can pop it up. I have lots if people want to try it.
