Interesting. Didn't know this product existed. Might buy some just for kicks. Already have plenty of PB Blaster and Kroil (my fav) but why not. 😂

I think this would be the main differentiator from other penetrating oils:

"…leaves behind a protective layer to help prevent rust and corrosion from re-forming.". Hmm…
