I sideswiped a white brick wall while parking in my work garage. I am devastated as the scratches it left are deep and it also left white residue from the brick. The series of scratches are about 3 inches long and cover a space about 6 inches high on the front right bumper. Can I use touch-up paint on something like this? If so, where do I get it and how do I apply? If not, does anyone know a less expensive way to fix this in the Washington, D.C. area? Thanks, Jonathan
