You might not be aware, but Baumgartner has a generally negative reputation in the conservator community. From what I understand as a non-expert, he's overly aggressive with his swabbing/varnishing and he's taken power tools directly to an artwork numerous times. The former isn't obvious to me either.

I've read that. I'm not part of the conservator community, I just really enjoy the videos.
