Didn't work at all---JB weld held to the socket very well, but didn't hold to the supercharger plug AT ALL. I think elmer's would have had a stronger bond. Going to try again---sand down the plug, get a rough surface, etc. It seemed to adhere to the plug's coating, more than the plug. Strange, the "black" coatings usually don't peel off like that, but a closer look at the plug makes me think it's brass.
