Re-Blueing a gun

Hi folks! I've taken on a new project of taking an old rusty 20 gauge and re-bluing it. I found a great kit to do it with too. Birchwood Casey makes the kit and they have kits for all type of firearm projects. The gun had a ton of pitting and rust all over. I was just going to touch up the bluing but when I got all the way into it, it stripped the whole thing. Here is the gun (Remington Wingmaster 870) after I have removed the bluing and rust. Nice nickle barrel. I'll post more pictures after the bluing!
