I bought a new, old stock helmet for the spare parts: pads, faceshield, and hardware. It was a good price just for that purpose. The helmet shell is an ugly pattern and color, so I was just going to discard it. Then I thought maybe I could paint it to match my bike or at least something more visible than what it is. I realize I'd have to use the proper paint type for the material, but that is true of any painting project. Has anyone painted a helmet and would you have any advice to offer?
