Nice catch, Beaner.

When I wash the car, I always use 35 psi compressed air to blow water out of the little areas (marker lights, door handles etc.) that hold enough to make waxing a pain. While doing this a couple of years ago, I noticed that water wasn't draining out of the wing depression in the boot lid (roadster). There are two small rubber ducts that carry water away and to above the license plate area. Mine were both plugged completely with....wait for it.... pollen.

Remember the thread from last year about cars "Green with pollen"? Yep, it gets that bad down here.

I use the low-medium pressure air with a rubber tipped gun to blow out those (gas door included) drains. If one uses this method, it also lets you know if the hole in the gas door or wing area is actually connected to the outside. You hear/see it.
