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.
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.)
Works quickly on stuck pieces. Loosens them really weLloyd. Makes easy work of rusted pieces
WD40 Rust Release not only works but...
It also prevent future rust. Great stuff!
Have at least 3 cans between the garage etc.
Used WD 40, many years and love the new penetrating WD 40 out now!
Another amazing product from WD!
I had a tie rod end jam nut that would not budge with all my weight! 220 lbs! I searched every blog on the web and tried almost everything others had suggested and still nothing! Bought this product today sprayed on when i got home, ate dinner then went at it, and presto!!
Awesome, works better then i expected
Picked this up to try it out on a project i had going. I needed to remove the motor from a pump on a pressure washer made in 1989. I was worried that the shaft was rusted to the pump, or the 4 bolts would be hard to break loose. I sprayed WD-40 rust release on it that night and let it soak for 24 hours. When i went to remove the engine from the pump, it was surprisingly easy. The bolts came off, and shaft slides out no problem.
I sprayed several times from all angles and over an hour and it never loosened the screw up enough for my power screwdriver in reverse to remove it. Waste of $7.00!
Moved about one year ago. Kept the WD-40 close at hand. Sure enough, needed it for the garage door and a rusted padlock.
