I have a C230 Sport Kompressor and 17" 7 Spoke single rims. I hit a massive pothole and consequently blew out my tire and cracked my rim. I was referred to a rim repair specialist and I am weighing my options. Do you think it would be sufficient to repair the crack? I have heard of doing it, but am nervous about what the outcome will be. These people came highly recommended by our top import auto repair specialist in town. Any comments appreciated. Thanks!
