Clay bar could have been contaminated. The paint could have already been marred. Weather could be cold and the bar is tough/hard. Paint is super soft... Lots of factors.
Tips: Use a clean clay bar. Make sure you handle it for a little bit before having it touch paint. Even try claying the windshield first. As you work with the bar, it will loosen up.
In regards to the clay lube, you can use water or detail spray or any combination of. I like to use water and a few drops of car wash soap in a spray bottle. Seems to work just fine for me. I doubt water caused your friend to scratch the paint. I have a feeling it was something else.

Correct, it was the mild bar vs the light duty white bar that comes in their off the shelf kit.
I have a feeling it's the nutrients in the water that caused the scratches and marring of my friend's paint. He redid the claying step, with quick detail this time and another new bar, iirc, and no scratches or marring. I'd rather play it safe and use QD spray.
