Martinelli is the lacquer guy, at least until OSHAA and the Rochester FD finds out what's going on in his basement. I like the Tung Oil/Linseed Oil stuff and lately have come back to Watco 'cause it's easier than 6 coat's of Waterlox. And, over MDF there is a certain unpredictability for oils, i.e., absorption. Soooo, lacquer would be best.
