BTW, it is Nason Urethane primer.
Yeah, you can. The only drawback is during the sanding process you'll likely cut through the primer and if the etch primer is exposed there's no putting more filler on that area. Etch primer is forever soluable and fillers shouldn't come in contact with it. Some epoxies aren't compatible with self etch primers.
