I use a air compressor also to blow water out of the seams but when i;m drying I use the Absorber synthetic chamois in one hand to suck up most of the water and remove spots then I go over the same area with a microfiber towel in the other. It even works on getting the water spots off of windows and I haven't used any window cleaner in weeks after the main wash and just wipe the windows off using both items. Been working great so far.
