I scored a nice lightweight mahogany T off the web specials that I'm anxious to start finishing. For you more experienced guys, what do I do about the
string ferrule holes on the back? It seems like they would fill up with grain filler and clearcoat. Should I mask these off somehow or leave them open and
just clean them out as I go along? One thing I thought of was putting wax in them so finish materials don't stick. My son has some wax for his
orthodontics that may do nicely. Does that sound like a good idea?
