tips for spraying primer

hey oldvart thanks again...one question though- would spraying 1-2 coats of high build be enough to fill in the solvent pop? and if 1-2 coats is enough, would a gallon of the high build be enough to do the whole care properly? I have been sanding gently as i block, so thats nothing new....just praying that i can say bye bye to this solvent pop this time and get the car in paint
