don't sand the shell! unless you intend to remove text or there is some serious scrapes & scratches. but in that case you probably shouldn't be painting that shell anyway.

make sure to soak the dissasembled shell in warm to hot soapy water to clean it real well & let dry completely.

I never thought about using a cup of warm water to heat the can for smoothness, that's a good trick.

You don't need to do the pre sanding, I wouldn't do it on the dmg case but thats just me.

I've used spray paint on a couple of mine and haven't had too many problems. Half of them though have been sprayed on the inside.

I highly recommend this over spray paint.

Vinyl paint is great. It bonds with the plastic, and dries nice and flat if you do light coats. You can find it at Autozone.

Sand it with a light/medium grade sandpaper and then proceed to paint it using spray paint that will bond with plastic and then seal it. Tada!

Thretris had a good post about this as well.

hell no don't use plasti-dip!
that's not paint anyway

use the same rules that you would apply to anything else you paint.

it might be good to try on some other things before you potentially ruin a shell too.

airbrush is the best.
spray cans next just need to be more attentive to what you are doing with spray cans.

Probably a stupid post but what is the best way to paint a gameboy? A friend of mine recommended plasti dip but I want to know what you guys recommended.
