Use the Krylon spray paing (Fusion) that's made especially for plastics, and don't worry otherwise about it. You can even skip sanding it. Don't use primer, go straight for the Krylon. It will fuse to the plastic and stay put over the season just fine, without hurting anything. You can buy this paint at any hardware store, Home Depot, Lowes, Walmart, etc.
I did this with my helmet last year, and the paint lasted the whole season. I think I'll add another coat this month anyway, just to freshen it up. To keep the spray from getting on the inside parts of your helmet, you'll need to get some duct tape (or some other real sticky tape) and some plastic (cut up grocery bags, kitchen trash can bags, saran wrap, anything that will keep the paint from the inside) and tape that on the inside parts that might get sprayed by accident. Or maybe you could stuff some aluminum foil in there. It's the inside stuff out near the edges that will get hit by the paint, and they just need to be protected. This is the hardest part - covering up the inside.
In another life I spray-coated some plastic baby dolls. I didn't use the special paint for plastic, just something in a can that was the right color I wanted. After several years the plastic started getting very very gooey, along with the color on top. It degraded. But this was baby doll plastic, a different kind of substance than the covering for your helmet. Fusion will work on the helmet plastic.
