hi all. I just repaired some deep scratches on my daughters 2004 Saab this's weekend. They were on the rear side bumper they were deep and horizontal I masked the area off in a rectangle to include the scratches I filled primed sanded and spray painted when I removed the tape the rectangular area was "raised " and noticible I m satisfied with the scratch appearance,but the rectangular area is more noticible then I'd like. Any thoughts of how to have this area blend better Also I have some overspray but I read that clay is best for this All input is welcomed .Feed back please
