I'll add that I dinged my front rim like that last May and never got it to where I'd consider it "good" even though I rode another couple thousand miles on it... and in a fit of "why didn't I do this earlier" I bought a replacement rim from Easton for a measly $65 or so and it arrived today. I'm willing to bet you can find a replacement as well, and if it's the same rim you can even reuse the same spokes etc.

Mine worked fine though for all that time but pulsing front brakes on a mountain descent... not so fun.
