OK. So, paint helps with metal removal.

Great.

So you paint the part. Wait until paint dries.

Remove the first layer of metal.

Paint again, watch it dry

Perfect for a union shop, I would say!

Ahh, this is a research trick, not a production process.

No matter what the PR Dept said.

There was an interesting article in R&D Magazine, with a video:

The mystery was always how the oil got to where it needed to be to
affect metal removal - it was hard to see how the oil could penetrate
into the solid metal that was soon to be removed. The video shows that
the surface is cyclically sheared and ends up in a chip that resembles
a stack of dimes, and no penetration into the bulk metal is required to
lubricate this process.
