Noooo! What a bugger having a polished rim. I expect most places who machine polish will do a fair job - the actual damage is the biggest factor. My brother kerbed his merc amg alloys , and due to the face being flat if you're being fussy you will always see the new polsied shape/angle. Hope yours is light kerbing.
If it makes it any better ... My spring snapped while stationary in a Mc 's drivethrough, I didn't learn because in the same drive through i too then kerbed an alloy - offside front - but just a 108 :-(
Good luck.
