Taped shut hood to headlight gap.
 

There was a 3/8" gap between the bottom of the hood and the passenger headlight and front bumper. A bit of water was getting in and soaking the battery, so some 3/8" thick foam weatherstripping was applied to various areas around the front of the car. Along with an existing upper grille block, this leaves the lower grille openings as the only open areas of the car.

It may be worth only 0.01 mpg, but it's still keeping air out of the engine bay!

That's a good mod. I did a similar mod, but I didn't have the right size weatherstripping, so I "double-decked" it in some places. I only did it above the headlights, but there's lots more places to button up.
