Testimonials

"I had an exhaust manifold with rusted bolts that were locked up hard and would not move at all. There were 3 bolts so I soaked 2 of them with ** ******* penetrating oil, and one with Promech. I waited about 20 minutes and the one soaked with Promech was the only one I could break loose in that time."
