  1. Have you tried to use some of these rust removal fluids instead or in addition to penetrating oil to remove rusted nuts? If they penetrate into the thread, I would assume removing the rust would help a lot with removing the nut.

  2. One thing that was missing from this test is to verify if these products attack other metals. For example, if you have zinc coated bolts, will the product eat away all the zinc? How about aluminium? You often have to remove rust from items that have mixed metals and you cannot use a product to remove rust if it destroys the other metals.
