Rear swingarm pitted and scratched. Sand it?

My swingarm on my 09 TCX is looking a little shabby with pits and scratches. How do I go about cleaning it up? I was thinking about getting the electric sander and some fine grit paper and going at it. Is there a coating on the swingarm? Any suggestions on making it look like new?
Thanks

Its a dirt bike. Buy a new one next year.

I know but I am freak when it comes to keeping my Huskies looking good. My 08 WR 250 was raced for a full Enduro season in the B class and still looks great!

lol up here it is literally impossible to keep something looking good unless you plan to do full rebuilds. Our trails just beat the piss out of bikes. I would think the best bet would be to put clear martac over high wear areas.

I use Scotch Bite type pads when I'm washing my bikes and sort of wet sand them while cleaning. Trick I learned with the Aluminum framed bikes I used to ride.
