I love it. What did you do to get the case to go from picture #2 to picture #3? I've worked on mine with a buffing wheel and aluminum buffing compound and still don't have great results.
I just misted it with Extreme purple degreaser. Than brushed it with a tooth brush until it was all loose and rinsed it off. than i blasted it with brake cleaner to get rid of all the grit. i didn't do anything to buff it. it was just in good condition.
