Professional Mechanics Formula Penetrating Oil
Promech, Professional Mechanics Formula Penetrating Oil is faster acting and more effective at freeing up rusted, corroded, or seized bolts, nuts, and hardware than anything currently available, retail or industrial.
Promech is not intended to be a universal lubricant, it is concentrated on the penetrating part of the formula.
After all the slipperiest substance on earth is not going to loosen that rusted bolt or nut if it cannot get in there to work.
Promech is not a lubricant as it works fast, thus evaporates fast due to its extremely aggressive carrier.
It has also shown to work very well in cases of “galvanic corrosion of dissimilar metals”, such as the seizing of a steel bolt in an aluminum block.
