Worked well everywhere I used it
I used this on the liftgate of my Lexus RX350 which had sat almost unused for over a year due to Covid. The liftgate would not raise automatically. I cleaned out the channels around the perimeter where the weatherstrip is and sprayed the hinges and lift support pistons with this product. It's now working the way it's supposed to. I didn't even have to work it in by opening and closing the hatch. I thought I might need a new liftgate motor and was glad I didn't. Lexus parts are expensive, and being retired I don't do much in the way of repairs any more, so labor costs were also saved. I also used this on my kitchen faucet on the quick valves. I sprayed them the day before I was going to change the faucet cartridge and they shut off easily the next day. I don't know if they were ever stuck because I had never operated them in the six years I've lived here, but they sure weren't stuck when I needed them to operate smoothly. My father was an aircraft mechanic trained in the military and always told me preparation and prevention were the key to successful maintenance and repair. Also worked well on the piston of my office chair. Highly recommended.

This beats PB. Got out 30 year old exhaust studs!
Decided to try this on a whim, have always used PB and saw this was cheaper on here so said why not. First job I tried it on were 30 year old exhaust studs in a turbo car, sprayed it on and did some other stuff. 20 mins later went back and the studs came right out, car had lived its life on the beach and was pretty rusted. Seems to stay where its sprayed and leaves a coating. Says it dissolves rust and I believe it. Got a stuck motor from sitting, trying this and fogging oil. Been alternating spraying them in cylinders, going to wait a couple more weeks before trying to move motor. Want to be sure the cylinders are really coated before turning it.

Good stuff
Used to remove a few bolts when changing out strut assemblies on my son's car. It worked like a charm.
