I wonder, if there was a machine, that could remove rust from under the car,
by traversing forward and rearward, spraying a rust remover, if people would
pay to have their under body de-rusted. I think the cost would run from $ 2000.00
to $ 2800.00. I think we could get 99% of all the rust.
Do you think this service would sell, as, opposed to "Frame off".
I can design and build the process. Is there a market for it?

IDK depends on the media. If it's a liquid "convertor" could be a bit messy. If it's a form of media blasting would it be able to get between the frame and body? What effects would either of those or your method (if different) have on rubber parst such as fuel, brake hoses and bushings?

There has been some wonderful developments in these past couple of
years with liquid rust removers. The Phosphoric acid techniques that have
sufficed for years, (navel jelly, etc.) are now considered a poor choice. The
newest processes actually "combine with the rust and eat it" or attach themselves
to the rust with a stronger bond than the rust has with the steel, and actually
dislodges it from the steel and the rust ends up in suspension in the solution.
Most of these new processes have a ph of 7, which means they are not even a
acid, so there is no effect on paint, rubber, plastic, hoses, fittings or electrical
stuff. Or, no more effect that water being sprayed underneath. Point is, we have
now reached a point where there are processes availabe that will "remove"
the rust safely, not attack it and everything else in sight. The chemistry is what has
held up automatic rust removal. There are porcesses available now. Now we need
machinery.

Well, I considered rigging something up with some PVC pipe, a pump, and a big bucket of Evaporust. I got the idea from a HOTROD article on a comparison of rust removal products some years ago. They made a spray bar with some PVC pipe and a sump pump to spray a continuous shower of one of the products onto a rusty hood.

There's also "Safest Rust Remover" http://www.ridrust.com/, and they also demonstrate a similar technique.
