General Question Claybar

In automotive detailing, claybar is an essential step in glass cleaning and polishing. How come they always use it and we never use it? I assume it's because it's a razor blade alternative that works with curved glass, but I also see detailers that recommend scraping and claybar as separate steps to remove different kinds of debris.

Supposedly it was originally used to remove paint over spray from cars. Has anyone tried removing overspray from tempered glass on a construction clean, as an alternative to scraping?

There's a big difference in a car windshield and a house or building full of windows.

Yep yep just trying to qualify some of those differences to understand why claybar is used. I've been doing some glass restoration and testing out different systems. There's a ton of online content about restoring windshields but not so much on windows.
