8ntruck 7,772 #3 Posted May 17 . Marvel Mystery Oil, Kroil, Rust Buster are other possibilities. Time is your friend here, too. Several applications over several days will likely be needed, as it took some time to rust up. 1 Share this post Link to post Share on other sites

peter lena 9,231 #8 Posted May 17 @John2189 very often refer to a lubrication creep , most of the stuff I see is rust bound , especially like the rusty cables that sound like a jack saw 0n a threaded rod , nothing moves , what could you possibly do ? regularly get after things that are SAPOSED TO MOVE , make the rust run out . 3-1 penetrating oil does a very good job , personally like super lube hydraulic oil , small bottle , on things that already move , keeps them that way , rust dust is your , heads up , pete Share this post Link to post Share on other sites
8ntruck 7,772 #9 Posted May 17 One thing I forgot to mention - trying to tighten a stuck bolt slightly will sometimes help to loosen it. Of course, if you try to tighten it too much the whole head of the bolt will become very loose.... 1 Share this post Link to post Share on other sites
