i remember a friend rubbing the lugs on his 82 dodge 4wd with a candle before putting the nuts on.said it made it easier to remove the lug nuts.
another friend squrited pink dish soap on the lugs of his vehicle for the same reason.
Someone showed me this about 5 years ago, but they told me to use canning wax. I have used it to extract studs out of old exhaust manifolds with good results.
