Recently noticed swirls in proper light which I suspect was due to drying technique - Cali Waterblade followed by Neatitems MF (suspect the latter as mechanism of problem) ? MF over surface in part dry from waterblade?. Have seen others comment on blotting technique - seems that this would not completely remove all water and any fine remaining droplets allowed to dry would leave a spot and then be zaino'd in. Similarly any technique that took a while would likely allow some drying with same water spot effect. Thought my initial technique was good until noticing extensive fine swirlling in proper sunlight which is in the direction that I only used with drying. I know there are swirl remover products but if I keep creating them with each wash and then have to remove will eventually be left with no paint. Need advise on how to dry properly without swirling or water spots on black car with use of zaino. thanks
