Thought I was doing everything correctly; 100% cotton mit from CMA; drying with initial Cali Waterblade and remainder with Neatitems MF terry then Zaino. Black Sapphire metalic; When done in certain light see lots of smear type swirls - definately tiny scratch marks, zillions! Gives it almost a wavy appearance in the sun if you know what I mean. Direction of marring is in direction of wash mitt or drying with the microfiber (horizontal across sides of car; waterblade and zaino in different direction - vertical and front to back). Suspecting the latter - MF towel. Probably drying incorrectly. Use Waterblade to push of much of the water. With MF then get rest, though in many areas there's not much water and perhaps wiping a fairly dry MF over the surface is doing this - would this happen over surface without much water?. Sick over it. Any thoughts appreciated.
