Good products. I have used them.

Rust & card for browning. Repeat until satisfied.

Rust, boil (or steam) and card for bluing. Repeat until satisfied.

I started with Pilkintons and tried others like American Rust Blue (rustblue.com), then Laurel Mountain Forge. The last seems more forgiving of not-perfect cleanliness.

In the winter during periods of low humidity I hang my parts in my shop bathroom at the end of the day, take a shower and leave them overnight. You can make a rusting box from a cardboard box and a light for a bit of heat.

The soft carding wheels and brushes are available from Brownells.
