"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 Penetrating Oil.”
-Mark Zimmerman, Motorcycle Cruiser Magazine
"I found their site easy to navigate and Moss Buster was just what I was looking for. The sprayer I received worked great on my patio and I will be a return customer."
-Mary, NexxChem Customer
"I just want to say thanks for the Promech Penetrating Oil. I had an exhaust manifold with rusted bolts that were locked up hard and would not move at all. I soaked the bolts with Promech, waited about 20 minutes and got the bolts out so it does work really good."
-Dennis B., Certified Mechanic
