Not So Slow Rust Bluing

I can’t believe it, but it’s been almost a year since I published a video. Dad life has really kept me busy lately, but i’ve started to find more time to play in the shop. last weekend I was able to sneak out into the shop and make this video about a topic that I find really interesting, rust bluing. Rust bluing is the process of generating  the red rust everyone knows and hates in a controlled manner, and then turning it into a black oxide finish. A black oxide finish is the the finish found on older guns, and lots of machine tooling. I apologize in advance, i missed focus in one shot, and I was rushing a little because it was super hot in the shop, and I was racing against nap time!
