I had a bunch of small, rusted-in screws that I needed to remove from my old steel window frames, I can't even guess how many decades they'd been in there. I tried removing some after spraying with other products and had to stop before I messed up the slot heads of the old screws. I decided to try out some WD-40 Fast Release Penetrant, and after saturating them and leaving it on for a couple of hours to be on the safe side, I was able to unscrew them. So satisfying. I reckon I would have had to drill them out if it weren't for this spray.I won't even look at a troublesome screw in the future without applying this stuff first. I wish I'd discovered it sooner.

The product inside the container is fine, I mean it's WD-40 we all know what that does as a de-greaser. But don't buy this version with this head! Buy the standard nozzle with tube that sticks in.For some reason they've decided to ship it with this rubbish head that just squirts WD-40 everywhere. Yep, some comes out the end of the straw, but the other half comes out of the swivel connecter near your hand. So what ever your sraying will get WD-40 but you'll also get it all over your hand, dribble down the bottle, and all on the floor next to what you're trying to spray. In the end I just had to throw the whole container away, just because they can't design a nozzle that works properly.

Don't know fi it was all in my head, but I think this stuff works! I had to remove a tow ball that I had tried and tried with no WD-40 or anything, then I sprayed this stuff on, left it for about 5 minutes... and then then tow ball nut came loose.
I had a number of seized studs on the back of a Navara ZD30 turbo that usually snap off when trying to change exhaust requiring additional hours of work to remove the turbo, drill tap and replace. I found that by using heat and then applying this, I was able to easily remove them. I guess that regular WD-40 might have worked, but this stuff certainly did the job.
I used WD40 Specialist for the removal of stubborn manifold bolts.I prayed the bolts the night before and let it soak all night then the next morning the bolts came undone very easily without any problems so I could replace my manifold gasket.
Taken awhile to loosen rusted on nuts and bolts but get the job done eventualy
Did not really do anything despite several applications between intervals...think normal WD40 probably the same.
Worth every penny!!! I bought this 6 months ago, I used it to remove rusty manifold bolts i was having trouble with, just spray and let it soak in for a few mins come back and what was super tight before should now be loose just like my ex.
I brought this to help unlock the locking nut on my microphone stand that'd been stuck for over a year. Spray, twist, done!Also managed to loosen up a squeaking door hinge.Great product, highly recomended.
