I know about the glue-wicked powerful stuff. I learned about it the hard way when I loaned out my GT to my g/f for the weekend and got it back a little "compromised". 1 new 1/4 panel later and you'd never know. When I visited the body shop I got a quick tutorial on it. Shop foreman glued 2 pieces of scrap for me and defied me to break them apart. There was NO WAY that was happening! I think I still have that piece somewhere in my barn....
