I spray the No Rinse (no wax) solution, twice, at least, before using microfibre soaked towels on the vehicle. I make certain that anything that is on the vehicle does and can dissolve does dissolve, during spraying applications as well, which may take a third spritz, depending... It is useful to wait, in my experience, several minutes between spritzes.
I had had my white S Modesta'd about 18months ago and brought it back to the detailer, who had applied the coating, for a recheck about 14 months ago. Only a few superficial scratch areas were noted-someone washed my car, despite explicit and repeated direction to not do so months prior to the recheck... Just sayin' At any rate, that worked well for me.
Thank you very much
