I wouldn't go near anything that combines a "wax" and an automatic car wash.. If you put a good layer of a top sealant on before the winter, you should never need to add a "wax" to the car. I put three coats of Zanio on the car in October as soon as I got it, and water still is beading like crazy almost 4 months latter.

If the "undercarriage" you talk about is just a wash... that's not a bad idea in the winter with all of the salt around... if is some "undercarriage sealant" that's not going to be worth it...
