Scott, be real careful about selecting touch-up paint for the keyboard. Many paints react to certain types of plastics and other paints. For example, acrylic laquers will blister severaly when applied over enamel finishes. You may want to check with Yamaha first to see if they have anything available. More often than not, Yamaha, at least in their marine division, will supply you with the appropriate, color-matched paint for a nominal fee.

Cheers,

Gary
