brass fallboard decal

[Owen J Greyling, RPT]

Dear List,

Would any of the refinishers on the list be willing to share a procedure for
the following?

 I am refinishing a grand piano with hand rubbed lacquer.  This particular
instrument has a brass fallboard decal that appears to be let into the
veneer, but at the same time, left slightly proud.

Is there an accepted procedure (or trick) to apply the sealers, colour coat
and top coats, that would leave the decal intact, yet visible through the
black lacquer?

Thankyou,

Owen J. Greyling, RPT.
