I have always sanded with 80 grit with a DA after sandblasting!! Primer is a mechanical bond and those scratches make a great base. Also DA'ing you get rid of any dust etc hiding in crevices ( microscopic ) that sandblaster made that air may not be able to get out. Not sure if I need to, I just always have and never have had an issue..
