I'm exceptionally protective of my paint. I only hand wash using the two bucket method, dirt traps, and continually adding fresh water. However, it is not aways possible. I have no issue using a touch less wash when there are no other options, I just don't do it very often. I manage to do a pretty darn good job of avoiding spiderwebbing. However, I would never dry the vehicle because it does not get all of the dirt off of the paint. It just doesn't and until I can get a hand wash on it, it'll always have some measure of dirt on it. All that said, it's useless practice without proper waxing and paint protection. Proper sealing and waxing the paint finish also is critical in minimizing scratching potential.
