Promech, Professional Mechanics Formula Penetrating Oil was developed and used by a small circle of professional mechanics, Hot Rod shops, and restoration professionals. It is now available to the public. Promech 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 developing 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 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. Like those nasty water neck bolts in your aluminum intake. Consider being able to save some of those irreplaceable parts on your old rod, instead of having to torch them off.

Years of field testing, and recent ASTM lab tests confirm Promech performs far above the competition.

Promech also has unique properties such as actually "fizzing" the corrosion out, as well as the ability to "creep and climb" into the seized fasteners. A huge plus when working in an inverted position.

A revolutionary advancement in penetrating oils!
