What kind of Devcon do you use?
This is the same stuff that Brown Precision used to send along with their stocks, used to come in 2 small tubes instead of the syringe, works OK, IMO, (but they now use AcraGlass):
Devcon Plastic Steel This is what I use now if I use Devcon:
Devcon Steel Putty Have you ever tried AcraGlass Gel either with or w/o powdered metal?
It's my 1st preference..........
