Lighter fluid
Lots of lighter fluid ................
Soak it in, burnish it in, polish it in. don't spare the lighter fluid and don't spare burnishing it in.........
I spend the average of 15 minutes burnishing lighter fluid into a pool cue shaft.
Then I apply several micro thin coats of pure polymer car wax .

I have to say, I have been woodworking seriously for over 45 years. I have been a member on numerous sites varring in many different mediums. I have read, heard, seen, used many different finishing methods and I am going to have to say this is the weirdest and strangest finish technique I ever heard. I am not knocking it because it evidently works for you. But to me I can not see any advantage to using lighter fluid anywhere near woodworking.
But again I am not knocking this but will advise others to get the procedure from Farmer before you try this. Not your prototypical finishing technique for sure.

Good luck.
Yep that's what I thought to when it was suggested to me ...........
I thought it was a bat $hit crazy Idea, totally in sane and a good way to destroy a cue shaft ..........
But I had to try it ,,, the first time I failed , not enough lighter fluid and I had zero faith in using lighter fluid on wood .
I figured what the hell least the wood I practice on will burn good ..
Second go around it was like I was a mad man squirting lighter fluid on the wood then burnishing it out and doing it all over again.
Either it was going to work or not but I had to try it.
John you are just going to have to try it ...
Now every cue shaft I make is done with lighter fluid and synthetic car wax ..
Only issue is on a cue shaft the oils from your hands with break down the wax and the open the grain of the wood .
Depending on how much the persons hands sweat, depends on how long the lighter fluid wax finish lasts .
Straight up, you have to be willing to really work it in like a 8th of a can of lighter fluid on one pool cue shaft..
As lighter fluid working on cue shafts or other wood workings .
Lighter fluid is clean and contains .
This part is a theory I think I know a little enough to explain why lighter fluid works.
Naphtha if I am not wrong has paraffin oil in it and its the paraffin oil that seals the wood pours ...
Form of petroleum oil, paraffin oil is a byproduct of petroleum and is what creates the BTUs in a diesel engine.
When it gets really cold diesel engines fuel filters wax up because they were running #2 diesel with has more paraffin in it then # 1 diesel fuel , but # 1 diesel fuel has less power .... less BTU's Less paraffin .
Sometimes the specialty naphthas are called petroleum ether, petroleum spirits, mineral spirits, paraffin, benzine, hexanes, ligroin, white oil or white gas, painters naphtha, refined solvent naphtha and Varnish makers' & painters' naphtha (VM&P) . The best way to determine the boiling range and other compositional characteristics of any of the specialty naphthas
The scent of lighter fluid doesn't linger after a while either ...
Its really nothing new in the cue makers world .
Some say it raises the grain, and it might at first but its burnished down pretty solid ...
