I bent my mirrorback "Ford" tag in the front, by most likely hitting a shopping cart in a parking lot. I just said, f*** the whole front tag idea, popped off the 3 fasteners, took off the tag holder knowingly that I would have 3 holes in my bumper. What works well to plug up these holes? ...and possibly the deep scratches where the sides of the tag holder rubbed against the bumper and the circles around the holes dug in by the tag holder? Tried Meguiar's Scratch-X. Thx.
