Best Rust Blue Formula For non-collector Luger refinishing?
 

I have a very good shooter Luger that is a completely worn mix master non-matching gun with a frosty, but accurate bore that I would like to refinish. I have Brownell's Classic Rust blue formula on hand and Art's Belgian Blue as well as Nitre bluing salts to do the safety and other parts that need to be strawed. I am leaning towards the Classic Rust Blue formula since it has a more blue black color whereas the Belgian Blue is more black purple. Any advice is appreciated. Thanks.

I did look at it thanks, but it does not directly answer my question.

Since you're looking for the simplest route, just use the Brownells, with a small amount of sodium nitrate added...it enhances the bluish tint.

Thanks and what is the best source or most common/easiest source for sodium nitrate?

Amazon and EBay both have it for sale.

Thanks, I will try to get some and see how it turns out.
