That stuff from brownells is a good tough paint too. Alumahyde or something like that. I’ve done several barreled actions and stocks with great results.
This is true. I've only done stocks but it's been really good. Order extra nozzles and clean out nozzles....they aren't very costly. There's a reason they sell extras.
One note, depending on what color you want, it's hard to tell exactly the tone of the tan colors until it's on the stock. I've got one I need to put another coat on...it's just to light.
