^^^ What Jeff said.^^^
If the dings are on your track, and they're deep enough to plug you might consider that an option. Most centers have agreements with their pro shops to repair that type of thing at no cost to you. Have them use clear ball plug so it matches the color perfectly, too.
Normal track wear is a minor resurface job, but some gouges are deep enough that if you tried to sand them smooth you'd have to remove too much cover stock, and I've seen unqualified pro shops leave flat spots on the ball by just working on one area.
