How to remove scratches from your iPod Nano

I got an iPod nano the first weekend they came out, it coincided perfectly with my birthday so who was I to tempt fate! I’ve been very happy with it ever since. You can't beat the price for a flash based mp3 player that holds 4GB. However it has gotten pretty badly scratched, and I haven’t been too hard on it. This isn't critical for me since I care more about functionality than looks, but it is still a bummer. 

After reading through many similar complaints, I came accross this great post from Todd Dailey's blog - Restore your iPod nano to new condition with a $4 can of Brasso. I am shocked that something like this would actually work but he includes some pretty convincing screenshots. I figure it is worth a shot, but I don't plan on going the 'ziplock baggy route'..
