Meguiar's Smooth Surface Clay Kit
I just got my MacBook Pro today (aluminum unibody) and it's b-e-a-utiful! I made the mistake of putting on a See-Thru Satin Speck Case...(DO NOT USE THESE...it caused scratches just installing and removing. Also, I've heard they cause lots of scratches from trapped dust particles. All in all, just get a nice neoprene sleeve for your Macbook and enjoy the beautiful sleek silver aluminum body!) ANYWAY...I had a small surface scuff on the top, and I was freaking out...then I tried some of the Meguiar's Smooth Surface Clay Kit...I don't recommend this for EVERYONE...but it worked for me. I added a tiny spritz of the Quik Detailer Mist & Wipe to a napkin, rubbed it on, and immediately the scuff disappeared...then I used the clay, and just rubbed it a bit on top (not hard), and everything's dried, and the scuff is gone. I really don't recommend using anything abrasive like toothpaste or Mr. Clean Magic Eraser or anything...the clay is smooth and non-abrasive...I've used it on my car too (when I ran into a mailbox) and it removed the mailbox paint and small surface scratches. Good luck!
