yeah scoring the the two parts to be glued helps tremendously. two smooth surfaces dont stick well. You have to rough them up a bit. Ive used ca glue and jb weld, 5 minute epoxy works great too. my only complaint about jb weld is it takes forever to dry. or was that just me ?
Thats exactly how I did mine. The first time I just glued the snaps directly to the armour. Didn't work very well. With the snaps fixed on the pieces of plastic 1st, then glued to the armour, I've never had one pull loose yet. I used 2 part epoxy...the plastic weld kind available at Walmart. Works like a charm. sets up fairly fast, and bonds very well.
