I epoxied the first coat over bare metal, then a round of filler then 2 K over that and now i am after the small filler spots then I plan another coat 2K than block. Keep in mind the sanding, i know it sounds like thick layers of primer but most of it has been sanded and sanded...the car is rust free but the flanges from the quarter and lower patches etc have filler, plus all the dings etc. there is more filler than I would have liked but it is rust free.
