Necro'ed thread, but to add in there, if you want to protect the brass to try to keep it from corroding, try Deft nitrocellulose spray. You can do urethane, but the original razors appear to have been protected with nitrocellulose lacquer. I'm still experimenting with waxes, but so far, I'm not pleased with what I have. (Cleaner waxes don't protect that well)
