Please take a pic and post it up...if you use one of those mobile companies they basically sand down the grind and touch up the paint. Issue with this method is it looks great for awhile but then you notice that brake dust sticks to where ever the repair was done..I know, I did this route and it was done at a BMW dealership. If you keep up on cleaning it all the time and waxing the built up dust it will still look good. The other alternative is dismounting the wheel and tire and have the whole wheel refinished which is about $150.00. This does not include the remounting of the tire and re-balancing though.
