Make sure you put the reg on hold
[backyard customz] tidy up the sharp bits on the spokes, and bog the gouges, then take a wheel into a auto paint shop and ask for a colour matches spray can. Mask the 'repaired' area and give them a spray, spraying a small amount on the unrepaired part in an effort to blend the paint. Probably no point fixing the edge of the rim as next time you get a tyre taken off it might all come undone, so just give that a sand/ light file and give that a spray too.

That will give you an 'ok' result, which will look better than it does now, but not like new or anything. Its a $30 repair compared to a possible $400+ repair. Hit one of the toyspeed tyre gurus up for a price for some new rims maybe, then flog yours off on trademe to subsidise the new wheels cost.
