> In the USA we use salt on the roads in winter,
Not entirely true. Traditionally, in the north-central and eastern portions
of the U.S. the roads get salted. Out west they typically use sand, gravel
or cinders (still not good news for paint!). Although now, in some western
states, they seem to be using new chemical compounds intermixed with the
traditional solids that may sometimes include a salt variant or a derivative
brine. So, perhaps you're right after all! Yikes!

Out in the American West, many state road departments spray magnesium
chloride on highways before snow. At the outset - as with many 'easy
answers' - this method was praised as easing snow removal and preventing
icing . Over-the-road truckers were especially supportive. Now we find that
MgCl is eating away wiring insulation and effecting under-chassis
electronics. In addition, reports are starting to come in that airborne MgCl
spray is eating the insulation off of overhead electric wires. In Washington
DC a series of manhole explosions have occurred in areas where MgCl has been
sprayed on city streets.
Just some technical thoughts, as most Porkchoppers don't take their cars out
in snow here in the USofA.

You are correct. Many states don't use salt in winter. Some states don't
even have winter! Around here (MN-WI) the salt trucks are parked on the
side of the road just waiting for the snow to start so they can start
dumping the salt on the roads. Years ago road salt was the biggest
import into the port of Milwaukee. My dark blue pickup is white with
salt film most of the winter.
My point was that rust problems not fixable, other problems are. A
rebuild is a long term repair, a rust-fix, no matter how well it is
done, will fail again, so rust is a more important factor that anything
mechanical when buying a car. I speak from experience. :(
But wait.....From your URL:
"The Californian Department of Transportation built a customized spray
bar that is capable of applying 25 gal. of solution per lane mile at
speeds up to 3 mi./hr."
and
"used by some highway agencies, including the Nevada Department of
Transportation and the Colorado DOT."
In reference to the chemicals:
"sodium chloride, magnesium chloride, calcium chloride, calcium
magnesium acetate, and potassium acetate."
So the salt problem is moving west?
Too bad. If people would learn to drive.........
Cheers.
