Plastic Repair

So, my frame sliders came a day too late. I'm a complete n00b to bikes. Was turning right from a stop, went to heavy on the throttle or something (all happened so fast). Bike went down on its right side and caused some some minor scratches

Wondering if you guys can recommend me some touch-up paint. Is it worth it? How much does new plastic go for? It's not bad, but definitely noticeable.
