Personally, I media blast, prime with HOK epoxy primer, do the metal work required, re-apply a few coats of epoxy primer, do filler work as required, sand filler to 220 grit, another 4-5 coats of HOK epoxy primer, Guide coat the 320 and 400 grits. Wet sand 400 (600 if a dark color), seal, base and clear.
Although there are any number of ways of doing filler (Bondo), I've always been most comfortable making sure that any filler is protected by epoxy primer on both sides.
Your car looks like a lack of any type of primer at all on the metal before filler was appplied. Not good. On a good note, I'm sire that it can be fixed properly.
