I'd prefer to use a professional grade sealer /sealant that's good for 6 months or more of 1x a week gentle car washings, or less frequent washes if possible, that will withstand blazing sunshine and summer heat here in AZ. Wax on, wax off is a PIA and time consuming., it gets dirty really fast here in the desert, wind and dust, all the time, then the monsoon season from July on through Sept. Hence my search for a synthetic paint sealant.
