A high solids black primer undercoat = should do the trick. Converting mahogany to black is a little trickier. Filling twice is = necessary. In the PianoLac system, we fill once, sand, spray = Primer/Undercoat, sand lightly, fill again, then spray again. This is a = lot easier than it sounds, because the filler applies with a spatula in = minutes, dries in 30 minutes, and sands like wood. Be careful if you're shooting lacquer. Too much undercoat or sealer can = cause the topcoat to crack. These coatings have no plasticizer and will = draw the plasticizer out of the topcoat if too much is applied. Avoid using auto body type spray on fillers like Feather Fill. They = build quick, but can ruin a spray gun if not cleaned immediately, and = can crack in a freeze thaw cycle (winter move). They're also incredibly = toxic and flammable. There is no way PianoLac filler and undercoat can crack or delaminate = because it isn't plasticizer dependent.
