I'm glad they didn't try to say anything by way of a conclusion on the color stuff... What they did say matches essentially common sense, mostly regarding thickness and elasticity.
I wonder if anyone actually has tried the experiment of finishing a guitar in NCL and then stripping it and finishing it in (roughly equivalent thickness) of poly that was suggested in the article... Furthermore, the article (or one of the Fender luthiers) argued that it didn't really matter about the material, but I'm not convinced. The interesting points about NCL (to me) were how it's constantly aging and changing over time. I've never personally experienced a guitar opening up over time that I couldn't explain with string changes, etc... But, I think it's perfectly reasonable to believe it's a real phenomenon on an NCL guitar. Poly... not so much.
