Okay this might be a stupid question, but i want to know what's the best way to repaint an engine. I currently have a Chrysler blue 360 that I'd like to paint orange. I've already cleaned it, but should i strip the old paint off first? If so, what should I use? Also, what is a good orange to use? I've had bad experiences with the Mopar orange so I'm wondering if there is something else I can use.
