Some anonymous butterfinger left a silver dollar sized dent on my Mazda 3 two nights ago. It's on the roof, about a foot behind my sun roof. It's got a small half-inch crease.
Urban legend: this can be fixed with an ice cube? I was told to put a couple of ice cubes in the well of the dent on a hot summer day. The shrinking dent well and tugging surrounding roof metal stand a chance of popping the dent out.
