Quick Detailer as water/wash replacement

What's everyone's view on using QD as a water wash replacement? I never used to be a fan, as I'm paranoid about self-inflicted scratches.

But now I'm warming to the idea, after using various products at car shows for a quick clean/buff.

Obviously if the car is properly dirty or has been out in the rain it needs washed fully, but if you've only done, say 50 miles in the dry, would you use QD to save time? I know of someone in America who is proud of the fact that there car has never seen water - either rain or a wash. They use QD all the time to clean the car

When we were at knockhill last weekend I took water ina pump sprayer hosed the whole car down then went round with a QD then a spray wax. I hate touched the car without it already being wet or rinsed
