I have a guy who bought a truck from his grandson that has American flag decals from the rear of the cab to the rear of the bed, the decals cover the entire bed with only 4 inches between stripes. He wants me to remove the decals and repair a place over one rear wheel arch. I think that there will be color difference where the decals are, can you guys give me some pointers on this? I don’t want to get into more than I can handle.
