Thanks for the replies. I guess we will clean it up and paint it. The bottom (exhaust end) inch or two seemed to have traces of red paint on it. Were they painted red at the end?
This tube has no baffle, it's just empty. Should we try to use steel wool as a baffle, with some wire cloth so the steel wool stays in the "can"? I know that we don't want to restrict the flow too much, but wouldn't it help (using steel wool) in keeping the oil misting down?
