Can I prime over bondo?
First off when you apply primer on body filler it will have a hardener. All primers have hardener whether chemical or natural reation.

Bondo Product Categories. Bondo products have been used in body shops for years. Bondo Fiberglass Resins and Repair Kits are 100 percent waterproof. Because they do not shrink, they are excellent sealers.
What doesn’t Bondo stick to?
Clean and sand or scuff the surface to prepare it for body filler — it will not adhere to smooth, dirty or oily surfaces. Generally, if paint will stick, so will Bondo.

Because filler is supposed to be on baremetal. You can put filler over epoxy but you run the chance that it wont bond. Both. Seal the metal up, do the filler then use it as a sealer before basecoat. Filler is porus and water will infuse it if given the chance, I dont want that next to the metal.
