Cavity wax, do not overlook this!

[foama]

After I parked the car outside on a hot, dry day, it rained during the following night. Next day it was dry and sunny outside, and I drove the dry car into the garage. To my surprise, the dry car started dripping underneath, and puddles formed. Further examination brought this to light:

The area forward of the windshield, where the cabin air goes to the inside, is drained into internal cavities. The water does not simply exit into the wheel well, but though an opening leading into an inside cavity. The water passes quite a distance and exits the cavity under the car.
The following pictures show where the draining water enters the cavities, and where it finally comes out. The black plastic covering was taken off during examination, and the pictures taken without the covering. Note the puddles.
I wonder if this is might be planned obsolecence...

We should not forget to include that area when waxing the cavities!

This area can be accessed through the holes on either side, just forward of the hood (motor compartment) hinges. You can see that hole on the bottom right of the first photo.

Btw: It is almost always better to do the waxing yourself, rather than letting "experts" do it for you. That way, you know what is done and how it is done! There are plenty of good products easily available.
