3M rubbing compound. I've had mine for a month and it has a ding in the passenger side rear 1/4, a few small cuts in the rear bumper, and a large through-the-paint-and-into-the-primer 7 inch scratch in the hood near the passenger 1/4 panel. The only thing I plan to do is toothpick some touch up into the scratch on the hood and live with the rest.
