You can use almost any kind of paint cause when you flip it to the view side it will look like you sprayed 20 coats of clear on it. I use a black gloss spray paint I forgot the brand and I lay down about 5 coats drying in between coats. Like I said it is a easy mod to do you just have to make your template first so you know exactly what needs to be cut. Tools I used; metal ruler, hold down clamps, masking tape, scoring knife, a Dremel (the modders best friend) and some spray paint and of course some time and effort.
