I've used it to free rifle barrels from actions that have been found in the ocean, in rivers and from military Mausers that were over 100 years old... if it doesn't do it, nothing other than a torch will.
KA is right on the money here. I have not seen another product that will come close to Kroil for loosening rusted hardware. Next is a torch, then a drill or EDM. There isn't a bolt out there that can't be removed, if you want it out bad enough...
I agree totally with this one! I have used my DeWalt impact drive for so many things I can't count. I know it will take out a screw or bolt when seemingly nothing else will.
