On the plastic areas of the case, vinyl dye works best. It's sold with automtive type items.
Does she hand paint or spray designs? Just use paint good for metal and you should be fine. You may want to seal it somehow too. Do a search in this forum for painting and you will get a ton of links and opinions.
Also check out Krylon Fusion for plastics - I tried Walmart (supercenter), 2 hardware stores, and 2 auto-supply shops, and there weren't any products labeled "vinyl dye" anywhere. NAPA auto parts had a catalog that did have vinyl dye in it (they didn't have any there) and it listed the colors that were available. The color selection isn't too great - greys, blacks, blues, whites, and one green. The Fusion spray comes in a variety of colors.
I like the Fusion spray - good color, and it dries thin. I ALWAYS have overspray when I use spraypaint (not a lot of practice; I only first used spraypaint about a year and a half ago) so there's usually drips in whatever I paint. With the Fusion spray, I do still get the drips, but they are usually very tough to see because of how thin the dried coloring is.
