If you live in MI, and you daily drive a car, you have to use a regular car wash, unless you have a heated garage with a floor drain with H&C running water to do it yourself.
Touchless car washes work in places like AZ (where I'm at right now) to get the dust off, but they are useless in MI in the winter. I've tried them a few times over the years, and they have been a waste of money.
You are better off getting the crud off and putting up with the fine swirls (which may not be bad, depending on the car wash you go to) and just do a good 3-step cleaner/polish/wax with a Porter-Cable in the spring. The slush/salt/crud is worse that having a perfect show-quality paint "look" IMO.
FWIW, my LGT was about totally repainted in July 2099 from a hailstorm. It's ONLY been through the local car wash since them, and looking at it parked out here after a local AZ car wash, I have no swirls, and this is on a very dark blue car. And when I got here after driving cross-country and through a nasty storm in IN, the car was white with a salt crust.
