Prolong Super Lubricants PSL40020 Super Penetrating Lubricant, 12 oz

I have used many different spray lubricants over the years. Not anymore. This penetrating spray is hands down the best I have ever used. It uses their patented metal penetrating formula to penetrate into the metal and form an everlasting protective bond. No squeaks and no wear and tear. I used it on a stiff, squeaking door and not only did the squeak go away, but the door also closes by itself. I recommend this product to anyone who hates squeaking and binding. Also good for stubborn bolts, nuts and screws.

Prolong has always worked great even removing rust

my fav lube, ok as a penetrant but a long lasting lube

No Joke! This product delivers! It may sound corny but it isn't because it is true. Prolong Super Lubricant not only met our expectations, it easily surpassed them. We own a custom van for the handicap. It has a folding ramp which uses two large hinges to extend and retract the ramp. This van is 11 years old. We noticed an annoying squeak coming from the ramp as we drove around town. It would squeak driving on a smooth road. We tried many products which would deliver a "temporary fix".We followed the instructions and were so amazed. We even noticed that the motor used to extend and retract the ramp wasn't under the strain it was previously to lubing it.We are so pleased we discovered this product. It's pricey...but it works! Would most DEFINITELY purchase this product again and again. Since our first use, we've had months of no squeaking! We didn't have to use too much of the product either. It will last us a long time.

I used to sell Prolong to industrial sites that needed the extra protection in metallic moving parts. It works on keeping corrosion off battery terminals. It rejuvenates air tools that have been losing power because of wear. It is a “one and done” on metal surfaces. Not designed for plastic! Loosen lock cylinders. Free up hinges. Use it on any metal joints to be lubricated. Yes it costs more but it does so much more. Use the liquid form in engines, gear boxes and transmissions. I also used to sell all of the name brands that advertised and convinced you to buy theirs.

I like this lubricant. Sprayed it on the back of the wheel hub and three to 4 pulls and the hub slid right out. def a must have in the tool box. If its sever rust to soak over night pb blaster and prolong are good to have. They both work and very well. Has to eat threw. pb goes threw a Styrofoam cup over night. Less mess you want prolong to now worry much about it on the hands, at least i have not.

Everything great about prolong now in a can with a solvent carrier. Get that same great anti friction in a spray can. Works great on guns! I use sparingly as it’s not cheap but it works good. I use this a ballistol and LPS 2 and 1 . Those are my go to spray lubes. And super lube cause it’s cheap and awesome.

I have been using this type of lubricant for around 27 years or so with out looking to see when they started, I have been using several of there products for years on everything from lawn mowers to swap coolers for the brass bearing (27 years still going same bearings) to all of my cars and trucks including my Dodge diesel Truck, this stuff is great.
