I dont ever plan on selling my computer so thats not a problem for me. Screw resale value, if people want to buy a stock computer, many people will sell them a stock computer.
I dont really see how I 'hurt' my macbook pro, it looks different, maybe if it has feelings now it 'feels' like an outcast?
I didnt sand over the iSight. When I was working on the finish the computer was completely disassembled. The only part I didnt remove was the trackpad, I covered it with a few layers of masking tape as I sanded the case around it.
Its back together now, at least until the new year. I cant afford the time to take it apart and do the polishing until after the holidays. I might even have to wait until summer depending on my workload throughout the next term.
Thanks for the advice on polishing alu. I have a bench grinder at home that I can get a buffing wheel to mount to.
