Bluing touchup - S&W revolver
I've got a S&W 10-8 that's in good condition, outside of some holster wear. I'm considering touching it up with some cold blue. I see that the Birchwood Casey Super Blue warns you to keep it off of the original bluing, but there's no such warning on Brownell's Oxpho-Blue. I'd appreciate some opinions on them.
I really can't justify the S&W refinishing... it's a shooter and I really don't want to have that much money tied up in it. I'm just looking for something that's presentable and provides some protection from the elements.
Thanks in advance.
