A few months ago I, ahem, backed the Tesla into Mitti's driver's side door, barely touching it but leaving a noticeable ding. Been bothering me for months, but I hadn't tried rubbing with dry ice to try to bring it out. Anyway, I had bought a set of Mitsubishi i-MiEV side moulding strips some time ago and, lo and behold, the strip perfectly positioned to cover the ding!
