I thought I'd throw this tip out as a new forum user. I like to keep my MacBook in great condition. One day I used some car wax on the lid and around the palm rest of my late 2009 MacBook and it made the plastic shine so well. I was impressed so much that I actually do this every so often to add some shine / thin layer of protection to my Mac. I'm wondering if anyone else out there has tried doing this as well.
