I am trying to replace the pumple bumpers on my 1994 Yamaha Wave Raider 700. I haven't had any luck in finding any that are black. I tried sanding, priming, and then painting them but as soon as I bump into something, it chips the paint. Does anyone know of where I can find something to replace the rubrail/bumpers with. they don't have to match what is on there. I am just looking for a black option.
