Anyone polish an LA timing chain cover before?

I dare say that the "Mirror finish polishing" was surface chromed (there is some orange peel in the low spots) and polished as I can't see how they got some of those places compounded. But hey, they are the pros.....I believe the fence post analogy was fair if you dont cut the original surface oxidation as polishing the OEM surface with mothers does not yield much, other than a smooth fence post.
