Well, the inevitable happened and I got a scratch on the leading edge of my front fender. I have the gray model, SCR95MGY. The dealer does not stock touch up paint and referred me to colorrite.com but their Yamaha choices do not include the 2017 SCR. Next stop was our local auto-parts store where their paint selection offered an almost exact match with Dupli-Color ACC0414 Metallic Graphite for Chrysler. This comes as an all-in-1 pen with paint brush and clear-coat sealant the other end with sponge applicator. A bit pricey but very convenient.
