Coca Cola... If I recall good, that was dissmissed as a myth on the MythBusters TV show...
Good job, got a close up look... did you polished them too. I was going to suggest you sand blast them, this will also give it a more satin look if you don't like the shinny one.
Grr you beat me to the mythbsters thing.
But didnt they use the coca cola to remove grease and oil from that truck engine? i dont think it was rust but it mite have been.
