Bought this to pull out a few small dings in my car door. Followed the instructions perfectly, and I did manage to get a very good bond with hotglue and the included plastic parts. I pulled and pulled but the dents did not budge. I tried using various sizes of plastic parts (there are many included) and repeated my efforts at least 5 times, but no luck. It's too bad as the actual tool and idea behind this is pretty neat.
