Cate,
I hardly ever wash my car. Maybe every two years!

A crusty base layer protects the car from all the salt and sand. A good tropical storm and a short drive behind a tractor/trailer truck and it's nice and clean!

I think from reading all of your posts, that you don't sweat the small stuff and can more than handle yourself up here. I don't know about handling some of the testy people in the forum though!
