My dad owns a body shop and we paint plastic all the time. Theres a certain material that you have to spray on the plastic before you paint it so the paint will stick real good. We use automotive paint not any of that famous ******* "Krylon Fusion". Also we put flex in the paint so when it bends or if you bump it pretty hard the paint wont automatically crack or chip off. IM not saying that it wont come off, but it reduces the chance of it a little bit. If you have this kind of stuff in your hands i would say do it. Im not goping to blink an eye when i think i need to paint the plastics on my bike. Krylon Fusion ids great too, thats why my snorkels black and not white and gray.
