Thread: Cold Blue Products - Whats best?

What cold blue products can we get in NZ? I know we can get the Birchwood Casey stuff, but the Americans seem to prefer Brownells Oxpho Blue. I look at the Brownells website, buts has to be shipped surface...can we get this in NZ? Are there any other products? What do people recommend?

At this stage I just want to do some touch ups.

Birchwood Casey put out quite a good guide in the from of a pdf file. Look for the section on metal refinishing.

The name of the game is preperation and cleanliness, cleanliness, cleanliness.
At best though I would rate the method (cold bluing) as only good for touch ups.

I have their liquid blue, the paste version and their touch up pen.
Each has its own use/results.

The liquid seems to give a darker almost black finish. The paste/goo is nicer to use.

Having read their guide, the biggest mistake I have been making is to leave the shit on longer than a minute b4 neutralising.

Stripped my little brno back to bare metal and blued it with Birchwood Casey super blue. Turned out just like a bought one...

Like much of the cold blues it will wear off quite quickly
