Chosen Solution
I dropped my Mac Pro in a busy street (on a rough cement). It is very rough on the edge. Cosmetic wise it is very ugly. I wanted it refined. How can I do it?
One solution is to put on a Hard Case Cover such as this one: New Black Rubberized Hard Case Cover for Apple MacBook Pro 13" 13.3" Non-Retina http://www.ebay.com/itm/like/22125813022…
You’ll need to replace the mingled parts since reworking Mac aluminum cases never gives satisfying results. Granted that the part that was damaged is replaceable at an acceptable cost. If you’re not very picky about looks and finish, you can try repairing it IF feasible and without danger to internal parts or the screen. If you do want to attempt to repair, start a question of your own because yours is actually a good one, and post good resolution pictures of the damaged parts. We’ll help you from there to figure out if feasible and how.
