Hi, Star Tech, In fairness to that FreeAll penetrating fluid. I have used that in the aerosol can and twice now over the past dozen years I had the experience of unable to loosen a steel fastener (nut and bolt) and a brass nut and a steel screw. I had given up after a couple of hours so I saturated them , said I would let them set overnight and if they did not loosen was prepared to just break the screws. I went out the next morning and the nuts were so loose I was able to unscrew them with just my fingers.
Now I know , Star Tech ,if anyone had told me this story I wouldn’t have believed it but it happened to me.
I am really surprised that FreeAll did not send you a new can of the product. I was so impressed with the product that after the first experience I ordered a case (12 cans ) (much cheaper)and have gifted them to friends who have helped me. They even sent me a free replacement can when the valve malfunctioned on the aerosolize can. They also made a non aerosol version which I did not think worked as well.
Star Tech keep doping what you do……I have picked up a lot of useful tips from your posts!
