Yeah, the Autozone nut buster ("OEM" brand) worked insomuch that I was
able to get the nut off. But it defintely did NOT "bust the nut"--at
best it dented it. The chisel also kept spinning around instead of
staying in a vertical position, which was very annoying. Fortunately
enough for me what it did manage to to do seemed to be enough for the
PB blaster to work, at least that is my theory.
