JB Weld is some wonderful stuff and it has many uses. But I have found that JB Weld is **** hard to adjust. I tried to turn a blob of JB Weld with an allen wrench in order to do some fine adjusting on my trigger for sear slop. It didn't work. The blob of JB Weld just sat there like a blob of JB Weld. So I tried again. No good. Finally I realized that JB Weld is glue. It doesn't adjust. It's intended for sticking to objects together. Using JB Weld to fix trigger slop is like fixing a broken car window with plastic sheeting and duct tape. It works, but don't try to roll it down.
