First of all, sorry for not getting back with you last night. Brother inlaw dropped by while I was just starting to hunt the stuff up. Devcon dosn't make a stainless steel putty compound. The do make steel bed and a titanium putty (looks like they may have dropped the aluminum putty compound!) The titanium is about twice the price for a pound of it ($80), but if your shooting a bench gun this weight factor maybe be your saviour. Plus titanium is much more durable than any steel compound. The two part tubs like they are using, if kept in a fridge will last quite awile. While the premixed anarobic stuff has the short life span. I keep all of my epoxy in a fridge, as it seems to last longer.
