Don't even consider one of the rust hider, oops I mean "converters", because all that crap will do is slow down and HIDE the rust and it will not do a darn thing to help repair anything. If you have that much rust unfortunately there is no easy answer but dipping the body would probably be the best way. Sandblasting would be the next choice but then there would still be the seams to deal with which BTW those super duper rust concoctions can't get inside them either. Obviously you are concerned about structural integrity, as well you should be, and the ONLY way to make structural repairs is to cut out and replace the metal. Rust is serious damage, VERY SERIOUS damage, and too many people seem to think that you can just brush on some kind of rust killer and that will take care of it but that is not the case. Even if you can completely stop it, which is highly unlikely, the damage AND the rust will still be there so removing it by chemical or mechanical means and replacing weakened panels is the only real solution. I have heard people say that "If I sandblast all the rust off I won't have any body left", well rust does not add anything so if that is truly the case the sad fact is they have nothing to start with since removing the rust will only reveal how much metal is already gone, and it will still be just as gone whether the rust is removed or not! Sorry to be so blunt but "rust on top of rust" is a HUGE problem and trying to make it sound easier than it is going to be would not be doing you any favors. Can you get some pics up of this thing?

I would suggest that if you REALLY plan to invest the money necessary to make 600+ HP, start by spending a few bucks on a rust-free shell to start with. 71-76 B-bodies really aren't THAT expensive. Alternatively, have it sandblasted and have new metal welded in if needed.

You didn't say where the rust was, or just how bad is it? Are there holes rusted thru? Is it just surface rust? .............
