The Japanese did not do an adequete job of rust proofing/rust resistant
design when they started importing to the US. The earliest cars sheet
metal was very thin and unprotected. They then shipped them across the
ocean without much regard to keeping the cars protected from the
elements. The rusting started while the cars were at the docks waiting
to board, and continued all the way to the states. US owners compounded
the problems by covering the rusty/salty metal areas with some form of
goo, and their cars disappeared before there eyes.
As for Ray's Blazer experiment, I coat the underside of my B with oil
every time I drive and it's automatic! :^)
