I have no experience with Gunkote but I thought it was an oven cure product. I don't have a full size oven that I can use to bake a barreled action so I stick with the air cure stuff and as long as the metal prep is done well the performance is quite good. I've tried the Brownells Aluma-Hyde and I still prefer the DuraCoat to that because of the long cure time with the Aluma-Hyde.
