I always thought swirls were from fibers in towels scraping the clear coat. Ya learn somethin new everyday. Time to buy a clay bar and some good wax.
it is...i don't think swirls are from wax..never heard of it..
if you don't use the right mit or drying towel or ANY towel, you're going to get marks and light swirls...
100% terry cloth towel all the time
and wash your mit in washing machine after every use and keep two handy if it's real dirty..one for underneath, the other for other parts..
it's all common sense.
if you're waxing cloth isn't right, it'll leave swirl marks...
