[More Dust than Rust]

I don't believe I said to paint the interior, but maybe you're just offering additional advise or ideas which is what I hope this forum is for.

Up here in the Northeast especially in the spring when the nights are cool and the air gets warm during the day, a lot of condensate forms on pans causing the outside to rust easily. Just figured it is easier for him to paint it on a bench instead of upside down on his back.

BTW didn't the original post start off with a recently flushed and clean engine? Somehow we have gotten into what to run in a cruddy engine.
