Simple answer, No.
More complex answer could go into pages dependant upon your knowledge of the chemistry that is behind the generic term Varnish, which I don't have by the way.
Most "Varnish" types would be too slow in drying to be practical in use I think, and the resultant finish would still need to be burnished once it had dried/cured fully (hours/days)
If my understanding is correct then a Varnish, in its most basic description, is just a blend of oils, waxes and driers, the blend determining the drying times and robustness when 'cured'.
Using something like Chestnuts Hard Wax oil is the nearest I would go to a Varnish I think.
I have never noted any reference to Pen Turners using an "Out of the Tin" product involving chemical cure technology either.
Having broken the 'Duck' in putting my thoughts together on this no doubt there will be someone with more knowledge on the subject along to point out the errors in my reasoning.
