Hi I have a product called demon shine rapid dirt shifter, however after spraying it and then pressure washing it away I can still see dirt on my car. I have do this 3 or 4 times until a thin layer of dirt is left, I then shampoo and dry my car. However I dont use wax or sealant etc, but I have now bought meguairs quick wax, will this make my car less likely to attract dirt?
