I saw your same question on another site and couldn't believe all the trouble some fok go to mix up a concoction to finish their bow. Tru-oil here, easy, stands up well and easy to blend if you get a nick and want to add a little more finish.
Here is a tip; only punch a pin hole in the aluminum seal after you open the bottle and store the bottle upside down when not in use, this will keep the finish in the bottle from drying out for months.
I build flintlock guns and whenever people talk finish some go to ridiculous extremes to replicate some violin varnish from the 18th century.
