"Bondo" is not the problem. Not killing the rust BEFORE filler was applied is the problem. Clearly the best solution is to cut out all rusty metal and replace with new sheetmetal and metalfinish without filler but FEW people have the skills to do it. Plastic fillers are not bad in themselves. However many inexpensive repairs are just filler over sanded off metal and the rust works its way back. It has to be neutralized and then protected from further rusting before filler and paint can be applied. Otherwise it WILL come back.
