Somone speculated that the drain holes in the unibody need to be kept clear...

you know, i think it was the 2 open drains at the bottom of the firewall (they're actually in the underbody, just after the transition from firewall to underbody) that caused the rust i've been fixing.

the outboard drain is perfectly positioned to receive tire spray directly into it, and once the water (salty water in the winter) is inside, it's not going to dry up quickly. the inside floor, firewall, and underbody of the car form a roughly triangular shaped cavity accessed by those drain holes.
