About ten years ago I was given a very externally tired 870. My winter project was painting the gun. I had used Parker Duck Boat Paint on boats and if you have used it you know how incredibly durable it is. I cleaned up all the rust which left all the metal roughed up. I stripped any remaining finish from the wood as well. I painted it with a brush using Marsh Brown as the base coat and went over the whole gun. I then used an artist brush and painted on blotches of Olive Drab. I then shadowed the Olive Drab with flat back which gave it a WWII camo look. The gun looks pretty much the same today as when I painted it, should touch up be necessary it would be simple. When I bring it in from the field on a rainy day I simply use a rag and 409 to clean it. It's not worth anything, but it's a functional fully camo'd gun. Along with being a conversation piece it is a gun I can take into the worst conditions and concentrate on the hunt without worrying about injury to a nice gun.
