can polish that up in about 10minutes yourself :-) Ofcourse you would be removing the clear coat but its coming off anyways.. But you will loose alot of metal :-) You scraped off a good bit... BTW it only cost me $120 to polish for rims a long time ago.. Most repair shops will charge you about $140 per rim.. But if you take it a polishing a shop they will be about $50 but they don't straighten it.
Maybe now you should sell your old SSRs and get some new 18's now that you have learned you lesson :-)
