[pianotech] How to remove scratches

[MICHAEL MEZHINSKY]

Thank you for expert advice. I am going to try French polish. Konig have $100 minimum order. I am going to give them a call and try to order one bottle tomorrow. Doug, what's the difference between brands of French polish? Local Rockler store sells some.
 
Thanks again,
Michael

Depending on how deep the scratches are you can eliminate or diminish them with 400 and 600 wet-or-Dry paper. Use water with a drop of dish detergent in the container as a lubricant.  Finish off with gray ScotchBrite or 4/0 steel wool and then give it two coats of wax, preferably Rain Dance Paste Wax.

The decal is buried under several clear coats of lacquer, so you are sanding this clear topcoat. If you rub thru the clear and exposed the black coats underneath, you will have to spray clear to build it back up. In which case, the whole fallboard surface would need to be cleaned and lightly sanded for the application of the clear coats. Then rubbed-out with the aforementioned procedure.

My advise is to place it in the hands of a refinisher. Because a spray can is not sufficient and rubbing out the finish to remove the orange peel or dust particles is not for the untrained. The scratches extend over the decal and if you rub thru and hit the decal...the whole thing might have to be sanded down past the old decal and new sealer, new black coats applied, new decal, new clear coats then rubbed out.
