Give me some sugar baby
I had my blue June 2020 build paint-corrected, full front PPF and full OptiCoat Pro ceramic coated when new. I've hand washed many times over the past almost 2 years, 21K miles and two salty winters, and have not experienced the same paint swirling issues. I use a microfiber covered sponge to wash, and terry towels to dry. Maybe your microfiber towels are too aggressive? Or the paint on your build was softer than mine?
Paint softness has nothing to do with swirl marks which would not extend past the clear coat.
