We have developed a penetrating oil, Promech, that is faster acting and more effective at freeing up rusted, corroded, or seized fasteners and parts than anything currently available. It was not intended as a universal lubricant. We concentrated our efforts on developing the penetrating part of the formula. After all, the slipperiest substance on earth is not going to loosen that rusted bolt and nut if it cannot get in there to work.


"For 45 years, I earned the bulk of my living twisting wrenches, and in that time I've come across more frozen fasteners and tried more types of penetrating oil than most of you have had hot meals -- and not once through all those busted bolts have I ever seen a penetrating oil that cut through corrosion better than Promech Professional Mechanics Formula Pentrating Oil."
