Well reading this thread got me to try some new things. Bought a Foamaster soap gun, a 20v rechargable blower, a high volume 2gal sprayer, a couple gallons of distilled water and a bottle of Mothers car wash (Has a GT on the front label so must be the right soap).
The Foamaster works great with the nozzle switching back and forth from foam to rinse easily. The rechargable blower is useless for drying a car, my shop air hose works better but still not enough. Wife loves the blower for quick garage, driveway and deck sweeping so we kept it. The distilled water spot free rinse works very well but does require a high volume sprayer, not my old bug sprayer.
Good news is that the car came out spotless. Quite literally. Even spots that were left previously that I figured I would need to clay bar to get off are gone. Great new wash method and very easy to do, just different than I had done all these years. Gave up on the blow dry and went back to my chamois which does not take that long and works fine. Easier than dragging out the gas powered back pack leaf blower.
