Here's the product that I use -

It's available from a number of suppliers on line, but shipping is a problem because it's a chemical and because it's heavy. You can check your local hardware stores - the big chains (eg, Ace) don't appear to carry it, but if you are lucky enough to have an old-fashioned family-owned store nearby, they may have it.
I use it several ways:
1. As a standalone finish. In this instance, I wipe on a thinned (1:1 in turpentine) coat, let it dry for an hour, and then wipe off any excess. Then, I wipe on several more coats straight from the bottle, wiping off the excess after about an hour. Wait a couple of hours between applications. After it cures for a few days (better yet, a week), buff.
2. To make a 'long-oil varnish' by mixing it 1:1:1 with turpentine and a good quality Alkyd varnish - I use McCloskey's. This is a wipe on, wait an hour and wipe off the excess, let it cure overnight, and repeat process. The result is very similar to Waterlox.
3. To make a lacquer-based friction polish by mixing it 1:1:1 with a brushing lacquer and lacquer thinner. Wipe on, spin at high speed while wiping to create heat, and repeat the process for several applications (I typically use three).
