yeah, the casted part of the rim was a pretty intense job. Had to take a grinder to it to get the pits out of it first (didn't even use paint stripper, as the grinder took this off anyways), then once I'd gotten past the pits, which was quite a bit of grinding, I sanded it down with about 100 grit sand paper, then worked my way up to about 300 grit, and then buffed em with an aluminum polish. Took quite a few hours, but it was worth it in the end I think
