I worked on it again last night. It's starting to get a good shine. I kind of cheated in that I only really polished the top, the only part you're able to see when it's on. I went from 400/800/1500 several times and looked at where I needed more work. I need to get some polishing wheels for my dremel and some rouge. I'm hoping that'll really give the shine that I'm after. The Mother's polish works well but only on surfaces extremely smooth. I tried it on my exhaust (Tanabe Hyper Medallion) and it looks brand new. I'm hoping it'll work well for touch ups once the rouge works it a little smoother.
I'll get more pictures up later. I have to use my car today so I have to put this back on for a while. I really want to do the valve cover sometime. Someone recommend it's easiest just to buy another valve cover and put it on when you finish. I might have to do that, but the major motivation for this project is that it's so cheap. It'll take a least a week and I don't think I can afford that much downtime on my car, either.
