Rated 5 out of 5 by selliston from Amazing Loosened my stuck wing mirror and seized compressor drain valve both within 10 minutes after hours of no luck with straight WD. One of the best purchases ever.

Rated 5 out of 5 by Leakyraft from Worked great! Couldn't get a rusty driveshaft out of a washer, to replace the bearings. Hours of hammering didn't budge it. Put the WD40 Penetrant around the rust portions of the drive shaft. It took a few applications and letting it sit over night, but the drive shaft came out with one hit of the mallet, the next morning.

Rated 5 out of 5 by Powerball Winner from Excellent for Automotive use I dreaded the idea of changing the oxygen sensor on my truck. It needed to be done and several people recommended spraying it a few days with PB Blaster prior to removing it. I had a free can of WD-40 Rust Release Penetrant that was sent to me a few years ago and I decided to use it instead. I sprayed it and let it soak for a few days. The sensor came out with little force than what I was expecting. I highly recommend using this for automotive car repairs.

Rated 5 out of 5 by Jack from Got the Job Done I bought a can of this several months ago. Recently purchased a used implement for my tractor (The thing was in decent shape, but a pivoting part was rusted in place). Sprayed affected areas with WD-40 Specialist Rust Release Penetrant and let sit for several days, then repeated the process (several times). Yesterday, I was able to work the part free. Prevented a tear-down/rebuild of this item, thank God...and WD-40.

Rated 5 out of 5 by Jayshetland from Great stuff So I bought a 5l drum and got a tester free. Stuff seems to work good on some rusty threads but works better on really rusty threads with a little heat not much but a little. Unlike normal wd40 this stuff sticks around to once the metal has cooled. All in all I'd buy it (just wish the tester had a bit more than two nuts worth of spray in to test further.)
