Well for experience tomorrow night will be far far to late. the paint gets a surface oxidisation within about 4-6 hours of claying a car and if you park it near a tree or heaven forbid a bird craps on it then your in trouble. I mean i know the megs kit uses detailer spray which does give some protection but i cannot stress enough how important it is to follow up with a good light polish and then either a wax or better still a wax and sealant. With a decent sealant you can almost get away with just washing it and then twice a year re-applying the wax and sealant. that way there is nothing for the crap to bond to.
