How should I address my lower quarter rust on a budget?

JB weld? Bondo bubbles? come on guys,cut it out, way behind the rusted area. then get inside, clean and treat the metal. If you don't have a mig, have somebody weld new in, then "bondo" the rest in yourself. Then you still have the paint problem...
It is not a cheap deal, with these old cars. Just do it right the 1st time, you will save $ in the long run. Oh, and when you open up that hole, be prepared to spend more. But, who else has one of these classics?
