if you want a good penatrant use aero kroil, everyone calls it kroil. its in a orange can and claims to creep down to one millionth of an inch if used properly (apply a few times a day, a few days before, but just waiting 30 mins does a decent job) its what we use on all the industrial jobs i work at. beats the crap outta the pb blaster junk and wd40
he was joking. :thumbsup: meaning that there's so little rust that even wd40 would work.
