To all who thinks there ain't bad epoxy out there....you're wrong. I've tried repeatedly to get various batches to harden using precise scales and shell reloading equipment just to prove my point to my LHS, as they were giving me a hard time about returning some that had been on their shelves since '97 (my fault for not looking on the original sticker). But the fact is, the average modeler shouldn't have to resort to these drastic measures to get a good cure. To think so is absolutely ridiculous. Yes, I agree; epoxy SHOULD cure as advertised, but there are bad batches out there that just won't cooperate. Hell, if this keeps up maybe I'll just go back to the Wal-Mart quickie syringes that I've NEVER had a problem with, although I'd prefer not to. Seems as though the hobby industry quality assurance/quality control isn't quite what it used to be. I'm done here.
