Bondo holds water, there for it will cause more rust. Primer will not stop rust as it does not seal it just covers the metal.
What you want to do is grind down the rust not sand it. This will remove all metal that has already started to oxidize. Now you most likely will not need bondo unless your filling in a dent. After you grind off the rust and get to good metal again. Just use sand paper and smooth out the metal again. Then cover with 3 coats primer, wet sand, then using a primer/sealer, then spary the color, finishing up with clear coat.
The only time you need to use bondo is when your filling in small dents. Your bondo should never be more then a 1/16th inch thick. If your bondo is thicker then that you did not pull the dent out enough.
I suggest you look at community colleges, or if your in highschool. See about autoclass. I know when I was in highschool, I took autobody repair. I fixed all the dents and rust on my 86 t-bird for the cost of materials. Alot of vo-tech schools have summer classes. If you talk to the teacher they may let you take the class and fix your rust at cost of material. This will allow you to get some education and get to use professional tools and equipment for the cost of taking the class. Which will be alot less then having a body shop repair the rust.
