I recently brought my car to a detailing professional with the thought that it needed a good wash and wax. Overall, I thought I kept my car's finish in good shape (although I dropped it off after a track day so it was filthy). I have to say, I was genuinely amazed at the results when I went to pick up my car. Here are a couple of 50/50 shots to give you a flavor of what was done...
(It should be noted that most of the scratches you see on the unfinished sides are microabrasions in the clearcoat. These aren't real noticable unless you are looking close but all contribute to a rather dull look.)
