So how good/bad is it to use Quick Detailer on a car that was last washed a week ago? On the plus side, it's been raining constantly so a lot of the dust, pollen, etc. has been washed off. BUT, even though there's not tons of loose dirt/dust on it, if I run my finger across it I can see there's a lot of dirt on it. So, if I use QD as an "in between washes" step, won't I be grinding that dirt into the finish?
