I want to get the under part of my se lip fixed. It was scraped when I bought it, down to the black plastic. What would be the best way to have this fixed and where should I take it?

Is there a plastic fill or would bondo be the only option? It's really not that bad, but I want it to look new

 

Honestly, you'll just keep scraping it.

If it bothers you that much get some decent touch-up paint, smooth the surface and then hit it a couple of times. Only you will know it's been touched up, no one is going to notice over three feet away.
