Had a play today with my first attempt at hot bluing and I can report back I have not suffered any chemical burns and have a partial sucess, its not as blue as i would have liked but its a manky old meteor barrel that was painted so sanded it down and gave it a bath!
Hopefully once i have the buffing set up things will improve but its still better than a cold blue and I now have a bit more info to get going. Still a way off putting something i care about in the blue so might have to start on the stock!
Oh also did the button I made up for the superstar and it came out ok. Everything is currently dosed in oil.
