Cold Bluing Cast Iron to prevent rust

[Doug Mason]

I may be way off base here, but in theory couldn't you cold blue a jointer table or table saw table for rust prevention--as opposed to using wax.

[Matt Lentzner]

You'd need to wax it anyway. Wax also keeps the friction down.

Cold blue is really great for some things, but it is not at all good as a rust preventative. Some formulations seem to even encourage rust. I've used it in some machine restorations, but I always wax it.
