[pianotech] Polyurethane finish on a stained mahogany piano

[Al Guecia/AlliedPianoCraft]

There is no across the board answer to your question. It all depends on the 
WB Polyurethane you will be using. I wouldn't trust anything 
over-the-counter unless it has been tested for your particular use. Check 
with a local chemical company that makes a WB Poly for comparability with 
the wood and stain you are using. It would be harder to repair than NC 
lacquer.
