I haven't found any product that will give a car a quick clean without inflicting some sort of maring, or at best smearing. If I can't wash the car properly, I'd rather leave it alone.
I assume your car is pretty clean to begin with, so seeing as there is a jetwash on site, I would be inclined to use it, use something like Autoglym Rinse Gloss as a drying aid, then all it will need it a pat dry with a towel and the tyres dressed. You'll be done in half and hour tops. Unless you are in the show and shine or concourse, then you'll need to put a bit more effort in.
