If the cap is on the soda bottle, I think it will burst.

Water in the bottle when the Great Stuff is first shot in will actually accellerate the foam reaction. Once dry, the GS is closed cell and has a skin on it, and shouldn't suck up and hold moisture.

My concern was more that the Great Stuff would simply be a physical barrier in the way of water that got into the car structure, so that it couldn't drain out the bottom.
