Swirl marks from going to 'brushless' carwash?

[polepino]

Hi detailing section!

Well, I get lazy during the winter months and even during most of the year actually and take my car to brushless car washes in between my hand washing/waxing/detailing all day washes. The thing is, when I wash/wax my car by hand I make sure to do all the anti-swirl mark things possible (i.e. different sponges/mitts for top and bottom of car, drying car off with microfiber towel, using zymol a couple times a year, etc.) yet I've noticed I still get the swirl marks in between hand washes(they do disappear after the wax initially). Granted they're not obviously noticeable if you were to stand a bit aways away from the car but if you get up close they get real noticeable in bright non-cloudy days. It sucks because I thought the brushless washes would help prevent this but now I'm suspecting, for some strange odd reason, that maybe the brushless is promoting it? Anyone have any thoughts on this? Am I not zymolling enough? Am I not washing enough?

P.S. I drive a BRG '05 MCS. Could it be the metallic paint?
P.P.S. Oh before I forget, my dealer washes my car every time I take it in for repairs also.
