Just to give the opposite end of the spectrum:

I am the swirl mark King!

My car is a DD that gets almost 4,000 miles a month on it, year round. When not driving it sits outside. It is constantly exposed to sun, rain, dust, pollen, bugs, smoke, debris, snow, ice, tree sap, bird crap, cats, dogs, alien scans and any number of other mystery materials. I want to keep in clean and shiny but don't think of the paint as some delicate flower that can't be touched or take some abuse.
I wash it every week with a microfiber cloth that I rinse out and hang in the bucket which sits beside my hose and then wipe it down with an artificial chamois that I also rinse and throw back in it's container.
Do I have swirls? You bet I do and if I look at it at just the right angle, squint perfectly with the precise level of light I just may see them.
Can I tell from just looking at the car from 2 feet away? Nope and nobody else can either.
If it was a garage queen or show car then by all means I would handle it differently but it isn't so I don't.
