When I got my MX, it was (and still is) unbelievably good looking for a 3+ year old car. The paint job (red) is phenomenal. What product do you folks apply after a wash to keep the surface looking new and shiny and most importantly, protect the paint job from sun, wind and other damaging factors? I've heard about the spray and wipe stuff (no buffing), but wondering what is a) the best for the car, regardless of elbow grease required, and b) the easiest/quickest/least time consuming?
