[Shiny]

I'm cleaning up a bunch of fasteners again so revisiting.

The options for inexpensive cold blackening products feels limited.

20 years ago, I used a selenium-based product that looked great... very black and no graininess. But no longer available. I suspect the coating was quite thin. Birchwood Casey sells similar products and I used one last year when I was on this thread looking for corrosion-inhibiting oils to put on as a "sealer".

This time, I'm going to try a Birchwood product that is also selenium/copper based but sold as a concentrate on Amazon so seems like a good value compared to the small bottles of stuff like Perma Blue and Super Blue... but maybe they are the same ???

Here's the product page: Link to "Presto Black STEEL PC9".



Anyone else used this recently?

I don't think it is as durable as a "hot" process like Parkerizing but I need simple and inexpensive.
