Thank you Brian and Foot Stomper. I have definitely seen that post before. That, combined with reading the back of the can and the data sheets I could find on the interwebs is what spurred my question.

The data sheet says max 1/4" and apply in layers, not all at once. Brian's post also made it seem like it was layered sort of deal. I will work one panel at a time for now.

I put epoxy primer down over the bare metal spots from welding and grinding, so part of my effort to get the filler on at once was to take advantage of the epoxy-filler chemical bond while I was in the recoat window for the epoxy primer. It sounds like I will be better served to abrade the surfaces as I come to them and not worry so much with the chemical bond.
