Cleaning up my father in law's TJ for Spring and recommended to him that we remove the fender liners for a deep clean. Sure enough, we encountered some decent rust behind them which I think we've caught just in the nick of time.

That said, how would you all recommend addressing? Cut out the metal altogether, or remove the loose rust and spray with rust reformer / POR 15?

You're looking at the driver side, passenger side is about the same.
