I just painted a couple things in my interior. Best paint I've run across is SEM flex coat. It was recommended to me by a local audio customization shop here in town. There are three products I always buy: the soap, the sand free, and the paint (in this case flat black). That was for the plastic panels...for the metal pieces I use a camo paint made by Krylon. It can be found anywhere....
There were several of those white spots and the cubby door was completely faded. I wish I had taken before pics but I just didn't think about it....here are the results....(sorry for the crappy quality, they're cell phone pics)
I plan on fixing the door switch covers next weekend, when a bunch of the stuff I ordered comes in. I'll try to post up full installed interior shots when I can get my hands on a better camera.
