Sealing the doors... what was BMW thinking?

THIS IS WHAT YOU DON'T WANT TO DO WITH YOUR DOORS!

Pictures of the right way to do it will follow.  :)

OK, I've done this before on a previous 2002... just put some caulk on the raised parts of the door interior, slap on some thick plastic, and away you go.  This time, I was curious about where the water actually comes from and where it goes when you do that.  Huh.  What I learned is that it is very easy to create pockets of water inside your door!  Handy if you like the taste of rusty, plasticky water, but not so nice if you're trying to make a dry car.  The second try has me using spray adhesive and plastic patches that are cut to size with much better results.  I've also learned that spraying the adhesive onto the door is just plain messy.  I experimented with spraying the adhesive onto a brush and brushing the goo into place.  Much better!
