[:0] Oooooh. That hurts..."Friends never let friends drive their SLKs." Now that the damage is done, though, I'd follow Shinigami's lead with the Scratch X and follow it up with some touch-up paint. At least it shouldn't be so obvious. Like you mentioned, you're probably going to be susceptible to a lot more scrapes if you're planning to lower your car. You might want to put some clear film under the lip in anticipation of future scrapes.

As far as the touch-up paint and future body work, I don't think it matters whether you use touch-up paint or not. The body shop will prep a much larger area than where the scratches are to make sure that the paint color blends into the rest of the car without being noticeable. My guess is that he'll do the entire underside of the lip and not just the area that's scratched. [;)]
