What's in a name? The witches said it first. "Macbeth, you're a Thane!" Urethane was ethyl carbamate first, but polyurethane is not the polymerized version. Confusing? Means that what you got as "urethane" wasn't really the same stuff that is regulated in fermented beverages, but a resin which was composed of larger molecules containing carbamate groups.
A lot of choices out there in finishes with (poly)urethane, oil or water based. If you still have your old container, check out the % of solids and resin, then match it and your solvent so you don't have to discard any tricks you may have developed with your former finish. You are, of course, obliged to divulge them here in payment for the explanation.
So there you are. Brontosaurus becomes Apatosaurus to clean up the family tree and our friend the roughing gouge is now referred to by the squeamish as a spindle roughing gouge because they don't know how to employ it properly. Life's like that.
