I go to college in boone Nc; we get LOTS of snow/ice/sleet. Sposed to get 9inches tonight. Anyway - all the salt that is put on the road kills my rims; i have alloy cobra-r replica rims. They get all rusty and grey in color. I bout some metal polish at wal-mart that works great, however it takes about an hour or more per rim to get it clean and shiny. Is there any spray on product? or anything thats easier and less time consuming? The product i have is a wool like material that you rub on and then off with a clean rag. Thanks.
