Black Oxidising

[Saul]

Has anyone one had much experience of black oxidising steel hardware, bolts and the like.    I have hot quenched a few bolts to blacken them and I like the results but I am interested in doing it chemically as well and have bought a kit to do the same.  I am blackening any thing that is rusty on my Sprint going with the Darth Vader theme.  

Just wondering if anyone else has tried this and have any info to share.

I use coolblack, try engineering tool firm. Every thing must be clean,,i sand/grit blast and use brake cleaner to de-grease ..cover the parts in Cool black and leave over night.

Once black enough remove and wash in deionised water drop in clean oil for and hour or so..Leave to drip dry, buff up. Or i used to use to do Ali stuff to but that used very

nasty chemicals that could and WOULD burn you, so i gave it all away.  But not difficult to do at home. As long as you a safe place to do away from dickheads.
