Check the Cowl Drain Tubes. They're a small rubber elbow at the extreme sides of the cowl's underside... inside the car. They then exit out of the kick panel. Those rubber tubes as well as the metal flange into the cowl CAN and DO spring leaks.
You can either buy replacement hoses, or substitue with PVC clear tubing. Shape tue tubing with a heat gun for the bends and extend the hose all the way down to the bottom of the fender panel and you'll eliminate a major rust problem on the front fenders.
The drain tubes only extend INTO the space between the fender and kick panel and not out of the car. As a result any debris washed into the space gets caught behind the front fender and eventually starts rust through holes.
