Polyurethane gradually penetrates into the cedar making it quite a though surface. I think in the case of Ramirez it works very well. The problem is with soft finishes. My impression was that the polyurethane on the '67 Ramirez grew thinner and stiffer by gradual outgassing and cross-linking. But whatever the mechanism, the Ramirez finish was much thicker and the cedar top was easier to dent when it was new than it is now, 57 years later. I have what may be the last of Tom Blackshear's guitars. He described building this one on the Foro, a spruce/Indian Reyes model. He described starting another, a negra modeled on Conde, but I don't think he finished it. Due to a problem with his hands, Tom did not French polish the Reyes model. He sent it to his neighbor in San Antonio, Tom Nuñez, who put a beautiful nitrocellulose lacquer finish on it. Blackshear said that after it was lacquered the instrument had to be re-voiced by sanding the braces some more. Blackshear had his doubts about this instrument, but after comparing it to my ´67 Ramirez and ´82 Arcangel Fernandez, he declared it fit to go out into the world. He offered it to me at a good price, and I bought it, curious as to how it might develop. When it was new the trebles very nearly overpowered the basses. While very powerful the trebles weren't as brilliant as those of the Ramirez or Arcangel. After a few years, and several hours of playing, the basses have filled in, and the trebles are much more brilliant. It has no notably weak or powerful notes. Overall, the instrument is quite loud. Of the guitars I own it is--for me--the best for playing both classical and flamenco, though it is neither the best classical nor the best flamenco. I attribute the change to two factors. One is the normal development of a new spruce guitar. The other, I suspect, is the maturation of the nitrocellulose finish. RNJ
