Best way to remove a door ding
 

Someone with a white car struck my black car with their door...

I can feel the paint transfer on top of my paint, but what is the best and easiest way to take care of this problem.

Call a Paint Less Dent Removal Company to take the ding out with out re-painting the car. Second get some wax and light compound and mix a little on a wax pad (50% wax,50%compound) wax the spot where the paint got transferred to your paint. That should get it off.

yep, PDR is the way to go. use some clay or polish to remove the paint transfer.
