A mate if mine wants to spray his shoei to a plain colour.
Any tips? Seem to remember someone saying certain paints can damage the shell?
Cheers
You only need to be careful with Polycarbonate injection moulded shells and as far as I know Shoei dont make any so you’re pretty safe there 
You can get a pretty good finish with rattle cans and a big helping of patience;)
cool, cheers
