I think most of the "printing" on the dash stuff is just painted onto the plastic surface. IF you still can see most of the instrument names I'd take a "metal scribe" (very thin, sharpened metal awl) and try to "scribe" (write over) the lettering. THEN, I'd take some white paint and put on these "scribed" areas THEN wipe the excess paint off. Let dry, apply another coat of paint.
Not hard to do, but tedious. :roll:
