Two days ago I posted up my detail job on the Accord. I did the same treatment on my wife's Jetta today. Interior vacuum then application of 303. Exterior wash with dawn (gasp) to remove old wax, then polish with Zaino AIO followed by a top coat of Optum OptiSeal. Results were great, it never had a lot of swirls or scratches since I only hand wash the car; however, there were some light water spots that the Zaino removed.
