What kinda epoxy do you plan on using. Proper application is epoxy primer then body filler. If you Use PPG DPLF epoxy, it has instructions to do it this way. bare steel can be in any grit from 80-180 before priming. The finer the grit for sanding the bare steel, the hotter the panel will get as you got more cutting power.
All body fillers, even all metal and duraglass etc. Contain talc, and non are waterproof. They are all hydroscopic and absorb moisture. This is why epoxy then filler is best. Typically most epoxies need to be wetsanded to make then easier to sand. I usually just da the area with 120 and apply filler, you can grind the opxy off and then apply the filler if you want. The epoxy might tend to ball up on the paper as it heats up from sanding.
