I did a BAD thing. I bid on and purchased a mold (Lyman 31141) on sleeze bay. A 4 cavity mould. When it arrived, it doesn't look near as good as it is pictured. He had to do a lot of heavy buffing on the outside to remove rust and the inside (in the moulds itself) shows some what looks like mostly surface rust. Is there a way to remove the rust without harming the mould inside?
