Ray Thompson of Kennett Square, Pennsylvania asks:

What would you recommend for a good brushing varnish, either oil-based or spirit-based for guitar? Or do you know of recent written material on this? I have tried Behlen’s 4-Hour Rubbing Varnish. It did not seem to dry hard enough on test pieces. I tried the French polish (shellac) but now I’d like to try a brushing varnish for its ease of application as compared to spraying or French polishing.

I have thought of trying to brush shellac. I read that if you do very thin 10% coats it can work. Then just fad level and spirit it off after build up. But that might be as tricky as French polish. I want a finish I can brush on, let dry a prescribed amount of time, steel wool it back; and repeat as necessary.
