Just look up a paintless dent place. They can take out most dents and dings. In SoCal, they prices are around $50-75 a ding (though I know of a place that will take out up to 3 dings per panel for $75) Just check around.
I also have a black MO... and got some dings in my door. I had a place called the Dent Wizard work on it... in 5 minutes it was gone.. but the technician was a perfectionish and spent another 25 minutes on it.
Can't even tell there was a dent. Highly recommend an experienced technician.
