It's hard to pick one representative example, but the whole channel is a better example than the video linked in this HN post. Where this video says things such as "using precision tools and carefully selected materials", Baumgartner walks you through what tools, what materials, and how/why he decides to use those materials in a way this video does not.

Baumgartner's videos are wonderful demonstrations of his skill and knowledge, as well as being entertaining. I can't imagine a significant fraction of prospective fine art restoration Customers would go seek out videos like these, but if one was considering Baumgartner a quick look at his videos would go a long way to closing the deal.

I'd say he's always been very secretive about the chemicals he use, what type of varnish was on the painting, etc.

I agree. For example, in this video they say "1% peroxide" to clean the circular ¿mould? marks. I don't remember any specific detail like that in the videos by Baumgartner, just "a mix of solvents", "some cleaners", ...

Been following him for a while. The recent one about the brush company was great.

I'm supposed to be finishing up a changelog entry for a software release, but this is fascinating. Watching someone execute their craft at this level is mesmerizing.

You did warn us though.

Was just about to recommend that same channel. In comparison to the article video, I find Baumgartners style much more educating and soothing. Though the process they use for restoring paintings seems pretty similar, it's always interesting to see new ways of doing things.
