Yes. Poly-ester is a common sealer/undercoat that builds well and is usually topcoated with something else that can be buffed out. Poly-urethane simply is a different component. Then again, neither one of those terms accurately and completely describes a finish, since they're only the names of the resins which are but one of the ingredients. Says nothing about the solvents, carriers, modifiers, driers, whether it's a two-part or one-part finish, and a host of other factors. Then again, some people's eyes glaze over when you start talking about horsepower and torque - same thing happens when some people hear some words that they associate with "plastic"...

All comes back to nitro finishes are fragile and the modern (since 1968 anyway) are more durable. There is so much hype surrouding nitro that it probably does affect the vintage market somewhat but I doubt if it will make a difference, say, for the entry level MIA line of "Highway One" guitars. Bottom line is do you like the way it looks? Do you care about how it holds up? And can anybody prove that it sounds different?
