my ront bumper paint is a mess, mainly due to dips on some turns i have to take. the paint has been scratched off low on the left side and a little bit up towards where the mesh grill is as well. is there anything i can glue on the bottom of the bumper where it makes contact with the ground to prevent paint to ground scrapage? if i get the bumper repainted i need a solution for this. also i tried to paint over some scratches on another part of the bumper and it turned out to look like 2 blobs of paint of a slightly different shade of blue. any suggestions or comments????
