Hi Chuck,

This is a few days old so you probably have an answer by now, but in

case you don't - we have ebony acrylic that was color-matched to Yamaha 

for this very situation.  You can also take something like a cheek block to

an auto-body shop paint supplier, who can make a match for you.  It

comes out great.

>Dear List - In repairing a chip on the front of a Yamaha fallboard using
the Schaff polyester repair kit, I got too ambitious with the 500 grit
wet/dry paper during the leveling out step and rubbed through the black in a
spot next to the fill. Since I'm only at 500 grit, I'm sure the problem will
worsen as I go through the rest of the grits. When I realized what had
happened, I decided I needed to stop right there until I was sure of what
steps I should be taking next.

I'm clearly out of my element here, and need advise. Do I need to spray over
the entire front of the fallboard, or just the side on which the repair is
located and feather it out,  or is a simple touching up of the rub-through
possible? What product or product and techniques would work the best? I have
a good compressor and spray equipment, if that would be needed.

My only concern is that the completed job looks right when it's done.

 Rarely does anything less than 75 years old come into our shop, so working
with hi-gloss ebony is something I hardly ever do. Words of wisdom from

someone in the know would be highly appreciated.   Thanks in advance, Chuck
