I've never had a problem with the top leaking, the top and windows are really tightly sealed on my car, so I don't think the pressure would be a problem. Just make sure the top is protected with Ragg Top or another such product that will keep the soap on the surface.

I would never run my car through an automatic car wash that uses brushes. That's just asking for surface scratches. The brushless washes, which don't do such a great job of getting the car really clean at least won't mar the finish, provided they don't use a strong detergent to clean the car. If they do use a detergent, it will strip the wax off the car, in which case, you'll have to wash and wax it again after getting it washed. Either way, it's not the best way to treat your Porsche.

The best solution is to find a water spigot near the house and wash it in the street/driveway with 2 buckets, a dedicated car wash solution and a nice, soft wash mitt.
