Had the same issue then started using more hardener and applying in a drier room and letting it sit for 7 days before use. so far so good.Only put one or two light coats on the underside our your action where it makes contact. I do this and then seal with one coat of clear, works just fine. However, I am not going to use duracoat any more for barrels and actions. On metal, I've found it to be just about as duarable as krylon.
