a_arnold -> urethane vs french polish (Dec. 7 2014 0:47:17)
I have a 69 Ramirez blanca. I have heard that their shop used urethane for a while after about 1967, but I don't know that for sure. My finish LOOKS thin and the grain shows through, but how do I determine what my guitar's finish is? Is there a solvent test I can try on an inconspicuous spot? I know alcohol will mobilize shellac but not oil-based varnish, and not urethane. . . any advice?

I would not try to use any solvents on your guitar. But if you have thin areas it can be touched up with some French polishing. Shellac sticks to nearly everything for touch up work.

Thanks, Stephen, but I meant that the finish looked thin, not thick and heavy like many urethane-finished guitars. It doesn't need touchup. I just want to know if it is a real finish or a urethane one.

Most factory guitars have really thick polyurethane finish but some are VERY thin too... to the point of being easily dented. Look on the neck joint area and where the fretboard meets the soundboard. Usually there will be a slight (or not so slight) kind of haze from expansion and contraction of the wood.

I have a '67 Ramirez blanca, which my wife bought new and gave to me. All I have to go on is memory, but when new the guitar's finish seemed thicker than it does now after all these years. The surface as I remember it was shinier and more uniform. Now the finish conforms a little to the grain of the cedar top. The finish seems harder as well. I'm not familiar with the details of catalyzed polyurethane finishes, but many resin formulations contain volatile compounds which slowly evaporate over the years. Jose Ramirez III used catalyzed polyurethane finishes consistently. I suppose it may have been possible to order a french polished guitar, but I have never seen one from the time he ran the business. I bought from the shop in Madrid and imported into the USA a dozen or so 1a classicals during the 1970s. RNJ

It is a thinly veiled truth that almost every kind of finish will 'shink in' over the years.

But would that thinly veiled truth apply to the rarified atmosphere one finds in the Jernigan Suite at the Emperador? Sorry, perhaps this has been discussed in greater depth, but I departed Samoa a day ago and have been in-flight since. Am overnighting in San Francisco and took advantage of the opportunity to check in with the Foro and read this post. Is it not possible that the Emperador has the unique capability to maintain things in place, with no deterioration or shrinkage? Would not the long-ago dancing Moroccan society ladies with scarves tied around their hips be linked to the thinly finished (if not veiled) urethane on guitars? If the guitars and the Moroccan ladies had resided at the Emperador all these years, would either have aged and shrunk? Would the scarves still fit around their hips and the urethane still be as thick? Stephen, while having dinner this evening at Scoma's I thought about heading to the Edinburgh Pub for a couple of ales, but I decided not to follow up on the idea, as it would not be the same without your scintillating presence to complete the evening.

Bill Bill, That was damned Hoyle of you to forestall going to Edinburg Castle, next time we meet in SF we will hoist a few rounds to Ronnie. As for the Jernigan Suite, I think the action of shinkage is the opposite of the physical reactions objects undergo if they reside in this most elevated wing of the Emperador. Be it guitar neck, or the fine waist wear of Moroccan ladies in waiting, shrinkage is the last action that comes to mind. In fact the re-engorgement of any shrunken membrane, be it urethane or organic can be effected by an overnight stay in the Jernigan Suite, the most potent and rare of luxury accommodations.
