Russ Fairfield was a guru about finishes.  The mentioned finish is called a "Oil Varnish Finish".
His info is covered about half way down this link.  https://www.woodcentral.com/russ/finish7.shtml

I have spent a fortune on finishes, the commercial versions from the big companies and from the little guys that create their own versions.  I have also bought components and made my own.  The mineral spirits and BLO are cheaper by the gallon and an opened can lasts almost forever.  The varnishes, spar etc., I bought in the small cans, because once opened it would eventually turn to gel.  I use a watered down version, watered meaning more mineral spirits for the first few coats to get better penetration and faster drying times. 

I have mixed many different brands trying to come up with a fast and easy finish, knowing there is NO such thing as a fast and easy finish.  But I can still dream that I will find it.   It is easy to stop at the big box and buy a can of Watco, either Danish or Teak, but more mentally exhausting to mix it myself.   Because I know that next "miracle concoction" will be the fast and easy finish I have been looking for.

Spray some "Bloxygen"  aka Argon into the container before you put the lid back on.  Argon from the TIG welder works the same.   Argon is a heavy gas the  blocks oxygen from the surface.  The finish will not gel.

I use a drop on the end of a finger, several spots on the area of stock I am doing, like a butt right or left side, then rub that with my hand until all joined, then move to another spot,
little drops of oil from a dipped finger, rub that in until done, move to another area, repeat until the stock is done. That is one coat. Never a run and an even coat is produced. Wait a
minimum of 24 hours for first coat, usually 48 is better. It must be hard and dry. After than using Tung oil, I only do one coat a day. I use WD40 for "cleaning" my hands of the tung oil
then wash with soap and water.

Great thread . I concur with Daryl .In my case I use my finger to swirl on a urathane based  spar varnish . Typically I buy the glossy for the deeper light penetration especially if it’s a nice piece of maple and use a wood floor finish called Arm -r -Seal. It's very tough and very water resistant , great if you don't remove your barrel for cleaning .
My pal Randy, a now retired gunsmith, clued me on to this as he didn’t have the time nor were his customers willing to pay for a London finish . Further he would wet sand the finish with more finish on the wet sandpaper once there was enough build up of dried finish . This did three things ,it smoothed the surface , filled the stock and added additional finish . This works great especially on hard -to -fill troublesome black walnut entirely skipping the sanding filler stage .
Really why would you apply finish only to remove it? ( vis a vis steel wool)
On other threads in this forum I’ve read where other stockers use the wet sanding the finish technique as well , so it’s hardly new .
It’s time proven and it works.
The gloss finish can be rubbed out to a dull finish especially if still tacky with your bare hand but the semi can't be polished up to the gloss.It can be finessed resemble a linseed oil finish .
