Smoothing out handrims

I developed an annoying burr on one of my handrims (I dropped the wheel onto cement). This is quite painful to wheel with if I do it wrong and don't have my gloves, or if I catch my exposed fingers.

I bought "Wet Or Dry" 600 Ultra Fine grit sandpaper today. I was looking for 000, but the customer who helped me said he did metalwork on vehicles and used that - and the store didn't have 000 as a choice.

Will this work to smooth it down? I believe the handrims are aluminum anodized. The only other thing I have in my toolkit (so far) is a round metal file, but that tends to work *inside* things better than outside them... :lolz:

Thanks for keeping this country girl rollin'!
