[pianotech] Polyurethane finish on a stained mahogany piano

[Delwin D Fandrich]

We've used Oxford "Premium Spray Lacquer," a water borne lacquer by Target
Coatings, on several red mahogany pianos with good results. I'd guess it depends
on the chemistry of the lacquer as well as the stain. If you need a barrier coat
you might try a light coat of shellac.

| The water based finishes do not work well with Red Mahogany
