I bought a component fairway wood years ago that needed a reshafting. I almost had to use nuclear weapons to get the glue to release and ended up scorching the crap out of the head. I asked the seller what he used to glue on the head and he told me it was JB Weld. After that I no longer bought a club unless I knew what kind of glue was used.
