Im sure your going to hear this more than once but, my .02$. Rust is
the reaction that occurs when ferrous materials (ie iron and steel) meet
with oxygen and moisture (water is part oxygen) the resultant material
is ferrous oxide, or (yuck rust) if you can prevent one of the two from
coming into contact with the other of the two then there can be no
reaction. plain and simple. if you remove rust from a surface, or even
if you remove 90 percent of the rust from a surface and then seal that
surface from moisture and oxygen there can be no reaction true? i takes
2 items and if only one is present, the underlying (sneaky) rust cant
promulgate itself due to the lack of oxygen. look at rust as a virus,
without a host and a catalyst of some sort, there can be no virus and it
dies. so does rust.

Subject: Rust elimination
Hi, listers;
In the process of restoring my GT6+ I have found some rust under the
undercoating on the front suspension sub frames. During the process of
eliminating the rust and painting the I got into a discussion with my
significant other's brother about rust. He has done extensive autobody
repair
as a hobbyist and professional and claims that you can't eliminate
rust.....it
will always come back. His treatment of rusty surfaces involves
sandblasting,
metal prep, bondo, etching primer and paint.
I take the opposite view in that if you can seal the metal against
oxygen and
moisture the (baring any penetration by impact or scratching) the
suraface
should remain rust free. I usually sandblast or wire brush vigorously,
treat
the surface with two or three coats of rust eater, prime, bondo, rust
eater to
seal the edges and then prime, and top coat. If it is possible I
undercoat the
inside of the panel and if possible fill the cavity with structural foam
to
prevent rust from the inside of the panel. I restored a 1973 Honda Civic
with
this method and rust seized to be a problem. It also sounded like a
Mercedes
when the doors were slammed. Obviously, I wouldn't do the foam thing on
an LBC
but I have a 1985 Chev Celebrity wagon that is a prime candidate for
this
treatment.
My question to the list is......what are your opinions in this debate?
Is rust
unstoppable once it starts? Or can it be controlled?
