Also for long term storage plenty of moth balls . Mice hate the smell at won't go around . Knew someone that did this he placed them on engine inside floors ,trunk and all over the ground . He did have to air it out really good but mice never got into his interior. He stored it in a old barn with a concrete floor . Oh he also poured Marvel Mystery oil right into carb while it was running . It would burn out on retsart in the spring . I guess this stuff is great for coating cylinder walls.
