looks like its going to be nice! You guys put epoxy down then filler over it? That's good, I see a lot of filler over metal these days lol.. One trick that i do is put down etch (on bare metal), epoxy, then a couple coats of urethane primer wet on wet, because the primer sands a lot easier then epoxy, and and you have more material on it so don't sand through as much when doing the mud work.. also its nice to have some primer on it to block right from the beginning
