Hi, I am the curb rash "king". But I hopefully have given up my
crown to a more worthy successor.

Both front rims got rashed several times before I finally learned how to NOT park this thing!
There's a thread back there that I started when I came to the Stinger Forum: asking how to go about "curing" curb rash. It was recommended that a wheel repair pro is the way to go. However, they are not cheap The lowest quoted starting price and time to fix was $125 and a day; it goes up from there in price and takes up to three days to repair damaged rims.
My methodology was founded on what looks good from c. six feet away. Wheels do not have any business in this world being more "perfect" than that, imho. So I used three grits of sandpaper; 200, 400 and then wet 2000. The wet polished the rims up nicely. Will they weather this coming winter? I can always convert these rims to winter only (I'm going to put winter tires on them) and go new for next summer. I don't believe that these rims will ever rust. But taking the clear coat off to sand the rash out will possibly compromise the sheen. A quick go over with wet 2000 will shine them back up. But if this gets to be a regular job I will tire of it quickly. So far, in c. three months, I have not seen any diminishing in the sheen of the sanded curb rash areas.
