Sometimes good intentions can become a problem as when Loc Tite won't let loose (or the wrong kind is used) causing a stuck screw. Rather than muscling it to the point that the slot is stripped, try this: find a screwdriver bit that fits tight into the slot, tap it in if necessary, tighter the better. Then heat the bit (I use a small butane torch) until it's red. Heat will transfer to the screw and soften the glue, making it easier to remove screw. Have don't this several times in my gun repair hobby. It works.
