I have had problems with my Z's wings paint job since the day I first washed it. It seems like everything sticks to it and leaves a permanent stain that will not come off no matter what I use. I tryed Meguiars Paint Cleaner, Scratch X, and etc., but still not even a budge. I am thinking of taking it to the dealer to let them fix the problem since I have the paint warranty that will protect against bug, sap, acid rain, and anything weather brought on. So will this be a wise choice, and do you think that they will be able to get it out? Or do you think I should just handle it myself and live with the results, which right now suck. THanks
