Anyone tried it to repair curb rash? Today (and I'm still beating myself up over it), I ever so slightly rubbed against the steal part of a sewer vent that stuck out of a curb and applied some minor rash to one of my Grey 21 RIMs. As my wife often says, it's the 'only you will see it honey' type. ;-) At any rate, it's about 2.5 inches long and on the very edge of the RIM. Likely less than a quarter of an inch wide. I'm debating having them done by a professional place (if anyone knows a good one in Montreal, Canada) or simply use the touch up pen and perhaps have the RIM redone when it's more beaten up. Experience with the pen anyone? Thanks.
