I did lots of these sort of boards (>20) and found
the method to work quite well indeed.
I used model lacquer, as would be used to paint
plastic car/airplane models.  I think anything that
is not water soluble would work fine, though.

Lacquer thinner/turpentine/acetone sort of solvents.

Good luck!
