Eastman stops using Nitro switches to Truetone

[Shishigashira]

I'll point folks to the excellent discussion AlanSam found over at Luthier talk. My summary of it is that the magic of nitro finish was that it was thin, and luthiers can now do that with Urethane and end up with a better product. I suspect no one will be able to tell the difference in tone.

And what about the forth coming Eastman-Bourgeois range? I wonder what Dana thinks? 

Well here's an article from Dana on finishes where he's mostly criticizing nitro, so I think he's already a convert to modern finishes.
