your best bet is gonna be just to buy a new quarter from honda. becuase that metal is probably pretty damn stretched and you wont get it smooth again if you try and pound it out. i hope you didnt mess up the rear panel where the lights attach.

Rice is a term thrown around by haters. Do What you want. I would suggest a somewhat subtle almost stock looking kit if you get one. But candy apple red would be sweet. And avoid huge vinyl decals.
