Except for releasing rust on bolts in the under body of your car.
Spray the whole can but only a blow torch to melt the connection rust will get that bolt out.
...and it's great on toes!
Yah for rusty bolts and whatnot on cars i use PB Blaster, though i do also keep a can of WD40 as well for minor stuff. WD (which actually stands for water dispersant) is just a lubricant while PB Blaster is a penetrating oil/catalyst and is supposed to break down rust.

if you have wasp nests all you have to do is hit the wasps with a shot of WD-40 and they'll drop like they were shot with a bazooka....ruins the nest for future residency as well.
Coke-a cola works good too....shits like acid.

It's actually alkaline so it works like lye....or Drano to give a more modern example. Everyone knows the Coca-cola trick to clean up battery terminals, right? It's one reason it ain't so good for your stomach....it encourages the over-production of stomach acid to neutralize the alkalinity of the soda. It's how many people end up with GERD and other heartburn-related issues. Anyway....sorry for the digression....water chemistry is part of my profession so....:dunno:
I've almost never used WD-40 in my life now that I think about it. Every time I needed a lubricant I always used a couple other things that seem to work better depending on the situation.
I'm betting he used margarine.
