I've done a couple of guns with Brownell's Gun Kote and they turned out well and it holds up. Beware that when you put it in the oven, make sure the wife is not home because it stinks up the house. It dissipates fast once you take the gun out of the oven but while it's cooking, it stinks. I have an 870 that I did up a long time ago for training. It's now my house gun. I'll post some photos when I can.
