I know Scott's tip about the low-pressure hose, but apparently my car's wax is almost nonexistent. Should I try this anyway? Also, if I understand correctly, using a terry cloth beach towel, then finishing the job with microfiber is the best way. My car is jet black, and I can still see water spots sometimes. Should I just go over these with my Quick Detailer? The last owner of my car obviously didn't treat the paint very well...there are microscopic white dots all over the hood around the grille, and a really shitty touch-up job done on the front bumper. I can't believe I've waited this long to wax the car, but I'm finally doing it. My clay bar will be having a hell of a time tomorrow.
