Not really. The MacBook Pro's aluminum is the look of, well, aluminum. It's not painted in the first place, so it would be very difficult to replicate the look. You'd end up making it look worse with any kind of paint. You can try to just clean it with a damp cloth and rub with some force, but that will bring minimal results.
Well my last mac got a mark on it and I t cutted it but it made it worse, I know they are said to be aluminium but there must be some form of paint or laquer as it wore through, any ideas guys ?
