You can DP prime it before or after body work. I live in the high desert and have a heated almost air tight shop so rust is not an issue, I do my body work first. but if I had worries about rusting in the shop I'd DP it first. bondo sticks as good or better to epoxy but it never made sense to me to prime it then sand and grind half of it away. but that is he common practice today.
Grinding the paint of is fast and can be destructive. I'd never do it. if you do really watch the sharp edges you can screw them up fast. use a good flexible disc and be careful. plan on extra primer to fill the scratches, and ugly shrink back as well. in a year or two . I can usually tell you who used a grinder , metallics especially.

Use these instead of grinding discs.Way less damage to the metal.

Don't linger in any one place to cause heat and warp.Get all the rust off,look close for rock chip rust as it will eventually come back through.Wipe down with phosphate before priming with something like Phix.Epoxy primer is nice but hard to lay on correctly...really tough to sand if you don't.

Since buying it I see thet Harbor Freight sells a similar tool for less:

... but with less selection in drums.
I plan to us mine when I get my truck moved to new residence.
