When changing colour of already sprayed plastic (lower grill), do you sand back to primer then spray...........or sand completely, primer again then spray

i sratched the paint up then i primerd it all up then sprayed it with the coulour
the sratching up is only to make the primer stick nice to it dont peel or anything
