Actually, it is not approved for automotive use on public roads
and highways. You can put it in your car and drive around your
own private property all you want.

No one said it was. The OP posted to rec.autos.tech, so it's
implied that he was inquiring about using it in a street driven
vehicle.

Pointless since it's sold in droves at any hardware store,
usually in the same isle as propane torches and soldering irons,
or, in with the camping equipment.

Cars have been high voltage and gasoline since 1975.
FYI, the brand name "Hot Shot" refrigerant is an acceptable
substitute according to the EPA.
What was it you said about "screaming" from the keyboard?

If you want to do something for spite, try robbing a bank,
there's more money in it.
