Not sure if anyone has seen this, but a cool video from National Geographic. http://www.youtube.com/watch?v=wYtj5FX4ZVI
There is a link to the whole show in this thread (page 2). http://www.ferrarichat.com/forum/showthread.php?t=259630
pretty cool. didn't think about 2 guys painting inside vs outside so it looks the same. notice all the prep work prior to painting...that is the key to a fine finish, but hard to not get in a hurry to put on the pretty part.
