Hey now.. Anybody ever try Bar and Chain oil for spaying in the door jams and around underneath? I hear it is pretty darn good for rust proofing..and that it kills the rust becuase of the phosphoric acid.. makes it turn all black.. Anyone try something like this? I'm actually about to do it myself.. What have I got to lose? I live here in the North East and I can't sleep at nights thinking about those ever materializing rust spots that seem to magically appear on some days. This is war.
