first, kick his ass... LOL.
second, try to get the dent out so you have (maybe not 100%) but cleaner slate to work with.
third, let me know how you do it

(I kind of bottomed out hardcore denting my driver side fender a few months ago -- ie. instant widebody styling)
btw - I noticed on those old Cressidas on that post from that dude who visited Japan that they had spot-riveted on fender flares and they rocked some deep dish rims, but not necessarily huge wheels, just wider. If you did some fender flares would you get bigger wheels like 17s so that they're tucked or just a little bigger but mostly wider??? I bet the handling would be schweeet...
