Yes I don't disagree at all that a good paint job works wonders,
but once it starts to wear down the ideal solution is to pull the
thing completely to pieces, sand blast it, and paint again. I'm
interested in whether these devices can help put that stage off
a bit longer, because it isn't going to happen.

I'd still keep grinding out and painting over rust spots where
they're found. In places I can't get to I've been spraying fish
oil, though I'm thinking about using these wax sprays for a more
permanent fix. Painting over fish oil has also lasted on the cab
of an 80s truck I tried that on a few years ago. New rust in
different spots has started to appear though, as it does.

OK. Some documents suggest it helps the zinc in paint or galvalised
steel to protect the steel more effectively, but there doesn't seem
to be a concrete theory.

These are 80s and 90s vehicles. All kept under roofs but open to
the elements.
