looking over my car today i saw something i never noticed i am begining to strip paint to repaint and i saw a decent size rot hole in the wheel well above the tire in the rear driver side looks bad to me not sure the process for fixin and how much disassembly this requires to repair

pretty common problem, spot needs to be cut out, and a patch panel from a doner panel welded back in.

not sure if the area can be accessed from inside the car, but if it can be, it should be resealed/painted on that side too after the repair is made
