Hi all. I am new here and need a little advice. I have a 1981 440LTD that I am going to detail. It has no oil or grease on the engine only scale I guess you would call it from being in storage for 20 plus years. How do you make these engines look new again. What do you do? Use some sort of chemical or just brush it down with a soft wire brush? I am talking about the cast part the jugs and engine case.Thanks :?
