Piano black is nothing more than really nice black paint. To get it to look nice you need to first get the surface smooth. Then you need to apply primer and wet sand. Repeat that last step many times until you have a perfecty smooth surface (the primer should look shiny and perfectly straight), then apply black lacquer in numerous coats and wet sand between coats (you may not have to sand between every coat). Wet sanding and buffing the final coat should make it look really nice. Getting a piano black finish takes a lot of time but it looks so sweet.
