only use airbrush or spraypaint for cases, but make sure to tape off all you dont want painted. If your wanting matte like you said, i like krylon. Duplicolor is good for glossy. Most case painters use auto paint, but krylon is stocked at walmart also.
Yea I was thinking of picking up a Purdy and going to town on my case. I use to tag for 7 years so I'm pretty good with spray cans. I just want to spray my MB tray black and leave the rest. See how that turns out and if it doesn't look good then I'll do the whole interior. I've been looking around locally to do anodizing too
I used some metallic silver spray paint from walmart, krylon i think but not sure. lol but im cheap I spray painted it, then I coated it with a clear sealent to protect it. works great so far.
