In my experience rust is fixable, but is in not a permanent fix. My
family owned a body shop for 22 years. I did a LOT of repair and custom
work. Sure, you can weld in patches or replace panels, but that won't
last very long. The factory starts out with clean steel, spot welds the
panels together, and then DUNKS the entire car body in cleaners, acids,
and then primer. The primer seeps into every joint between 2 panels. It
is impossible to field duplicate this process. Once major components
like rockers, heating channels, floor pans, frame tube seams, etc. start
to go, you won't stop it. You may slow it down quite a bit in the repair
areas, but the rust you just repaired is only an indicator that the rest
of the car will soon show rust in other places. It just does not happen
in the one spot you can see. Car bodies rust everywhere, just at
different rates. rustproofing compounds require flawless and COMPLETE
application to be effective. Even then, the rustproofing will only stick
to clean primered/painted steel. Again, difficult to duplicate in the field.
Beetle restorers know this well. They try to find "pristine" units to
start with that have absolutely no visible rust on them anywhere. They
then remove the body from the pan and sandblast everything to get a good
look at the external welded joints and seams. They run long handled
mirrors down the heating channels to look inside. I saw one shop using
miniature cameras. Once done, some restorers reject vehicles at this
point because, upon this inspection, rust has already started up all over.
That said, it is fun for some folks to undertake these types of
projects. You can fix a bug up to look good for a year or two, and then
decide whether or not to repeat the process when the rust starts to
reappear. Just be sure to manage your expectations. Some sheet metal and
bondo won't yield a $20,000 show car.
Good Luck,
Mike
