My 1987 944S has the under paint rock chip material covered with the body color paint. I've got rust under the chip guard material on the right rear quarter panel. I suspect it has gotten through from the inside and some ot it appears to have infected part of the fender where it folds into the wheel well. There's a smaller bit of paint bubble rust on the back that I'm confident I can handle myself but I'm not so sure about the fender / wheel well bit as this is going to be more than a sand & light fill jiob. Suggestions?
