I didn't notice any spots in that area that needed any rework. I did 2 coats at the time. The only spots were in back and front of the rear leafs where heavy tire spray was abrasive that needed some minor attention.nothing worn off near the exhaust area that gets hot and stays hot?
that was a bad spot on mine, right near the cat behind the rubbery tar coating
i think i found it in time and put quality paint onit so far no peeling or lifting after a few years
