IMO it *can* be done, but that's not counting the inevitable things that happen (stone chips, "deer incidents"

) if you actually *drive* the vehicle.
IMO the "swirls"/"spiderwebbing"/etc. that people are always concerned with is about 99.9% wash-related (I'm not considering special cases like people who live by a desert). I've never had marring of this type from just *using* a car. Learn to move the dirt off the paint without rubbing the dirt *into* the paint and you shouldn't have marring.
But that's not to say that everyone will find it worth the effort. It takes me a few hours to wash, and I can't be inattentive for even a moment. Gotta contantly consider the pressure of the mitt against the paint, the flow from the foamgun, the dirt on the panel and how it's reacting to my washing, and all the other factors that can contribute to marring. It's a lot of work. Imagine spending as long washing *one* panel as you might usually spend washing a whole car. Unimaginable? OK, I can see that. But it takes me hours longer to wash "right" compared with a "normal" two-bucket wash (which I can do as fast as anyone, but not without some light marring).
Every now and then I'll still mess up and cause some marring despite my efforts. But nt often; I don't have to polish more than once a year, if that. If you don't rub dirt into the paint it won't get marred. If your paint keeps getting messed up you're either gonna have to learn to live with it or polish all the time and run out of paint. Or learn how to avoid inflicting the damage in the first place.
Besides technique, there's frequency. The longer dirt stays on the vehicle the harder it'll be to get it off without marring. How often do you really want to wash, let alone wash "correctly"? Life is short ;
ANYTHING that touches the paint creates marring. That goes for towels, pads
Well, I wouldn't go that far. There are plenty of things that are softer than automotive paint (a wet sheepskin mitt lubed with carwash solution, for example). YOu can inspect with a 30X lighted magnifier and prove to yourself what is/isn't safe. And note that when people test things on CDs, for instance, they often test the materials *dry* even though they'll be lubed with product in actual detailing applications. It's the *dirt* that usually causes the problems. By all means eliminate the obvious offenders (coarse synthetic mitts, etc.), but then worry about how to safely move that dirt off the panels.
