I recently acquired an unenhanced Apple IIe. It has the painted plastic versus the colored plastic. The paint has chipped off in a few places, and in one place it looks like the previous owner attempted to clean something off of it and took the paint with it. Physically it's in excellent shape, not scrapes, cracks, or anything. Just needs a fresh coat.

Should I strip the old paint first? Prime, then paint? What type of paint should I use?
