That's correct. The epoxy will seal the metal from the moisture in the air so it won't rust. "Bondo" is then applied over the epoxy. This keeps airborne moisture from filtering through the bondo (which is very porous) and getting to the bare metal which would result in rusting everything from the inside out. The "bondo" is then sealed with sanding primer after it's shaped.

Good luck with your work.
