Can you apply the optimum spray wax when the car is still wet after a wash or better on a dry car? Also, better to spray directly on surface rather than onto microfiber towel or foam applicator to apply?
I use OCW on damp paint and have done so for a couple of years. There might be a decrease in durability but it so far has not appeared to be significant. Last year my car was only washed 3 or 4 times. Each time OCW was used on slightly damp paint and the beading lasted just over 3 months. Car is kept outside 24/7. I would say 3 months is not bad at all for a very easy to use product
