Just a heads up for all 997 owners, I took my front wheel arch liner off to fit a new front lip and I found an area of rust that has started to come through. It's mainly on the arm behind the duct for the front rad/ AC condenser but there was also a small amount starting on the body to the side of the froot. So mine has been dremeled and rust treated before a splash of wax oil to try and keep it away for as long as possible. My car is garaged and done 60k so if yours has similar millage you might want to have a look before it goes too far.
