Nick, (or anyone ��) all the directions I see advise spraying HCW on a wet car and using microfiber towel to dry (base) or spraying HCW and power rinsing off (on going) Is there a downside to using HCW on a dry, clean car? Or is the whole point simply for convenience? I tend to wash at the local hand held car wash but “wax” at home in the garage so using HCW dry is more convenient for me.
thanks
Ken
