black or white

we began spraying the cds with enamel paint yesterday, however after planning a systematic way of regulating the spraying (so none of the cds after being blanked end up in the wrong cases) we realized that after 2 coats of white paint you could still see the artist. So we have decided to use black spray paint instead. It will still cost us alot in Spray paint, but hopefully we wont have to use 2 coats.
