i had my whole bumper repainted and they sprayed the whole thing red, even the grills. i want the grills to be either white or left alone in their aluminum finish. how can i do this? should I just try to sand off the top coat and respray the grills again? btw, this is a ww big mouth front.

 

take it off the bumper and respray, or mask off areas and respray. no need to sand off in this case.

 

Re spray the areas that you want done.
