I've painted all my slot loading Pioneer drives black and I've done a couple of tray loading drives. ALL of tehm come out PERFECT and look like they were made that way. Pro all the way! All you need is some Krylon Semi-Flat black paint and you are good to go. I'm glad you are painting your drive because I've seen people get cool black cases and still have beige drives in it. Just gay as hell! And YES, take the ENTIRE face plate apart and paint each part individually. On the Pioneer drive, you'll need to take the button, LED cover, and the felt off (the slot filter). Now just paint each part separately and your good to go.
P.S. The Semi-Flat black color will match black cases but not the Antec SX1030B charcaol black (grey, if you ask me) case.
