I bought this over a month ago but only got around to using it this morning.



The idea is that it is a wipe-less silica spray. You spray it on the car right after washing & rinsing the car. I was away for two weeks & the car had not been washed for a week prior to that. So I started with a rinse, snow foam, rinse & then sprayed this on the car while it was still wet (mixed in a 1:3 ratio, HydrO2:Water). Then I pressure rinsed (as per instructions) the car. I initially made the mistake of not doing it section by section, you could see more water marks in these areas. Easy to sort & doing this section by section solves it.

Let's see how it performs.
