Will poly get age eventually?

Play it hard.

It looks like a '70s-era instrument. Thick '70s poly can be quite thick and quite brittle. I've seen old Japanese instruments from the era with long crazing in the finish, or a sort of 'shattered toffee apple' look to any dents and chips.

I think a 2018 poly finish will be more stable than these '70s finishes. This means they shouldn't discolour as readily, or separate away from any under coats or the wood itself.Never say never!

Buy a black Squier Affinity body from Ebay, and try and sand through the clear and the black. Under there you will find a thick sealer coat as well. I've tried it a couple of times, and it is impossible work.
 
Extremely slowly.

I played a ‘92 Stingray for at least 10 years day in day out.

Only the area right under and below the g-string showed some wear due to the slapping/popping I used to do... day in day out...sorry for that.
 
Aged olympic white ('78 Jazz Bass):

What I find kind of confusing: it is not white under the neckplate, just partly. But this area was never exposed to UV-light.

I posted a pic from the aged headstock above, here in comparison a Squier JV headstock from 1982 that has seen as much light as the '78 Jazz and only 4 years younger:

But one more factor: the windows in most newer or renovated buildings filter UV light. This wasn't the case back then...

Can anyone with more knowledge expound up on the difference between polyurethane and polyester?

I see so many references to "poly" (I've made them myself) but it seems like folks aren't specifying which.

One other slightly related point. I put a brushed-on Minwax polyurethane on a bunch of pine IKEA shelves. Poly like this seems to start with just a hint of yellow, but In just 8 years they are noticeably yellower than they originally were and notably yellower than the un-polyed shelves. All this while being in an attic with almost no sunlight.

I have a few of the same shelves of about the same age that didn't get the poly as a sort of control group so I know it's not just the predictable wood changing/darkening which has happened just a bit with the un-polyed wood.
Having been in the wood flooring industry for the last 15 years, I'm really familiar with various polyurethanes, oil base, waterbase, and UV cure. Had never heard of polyester finishes. Googled the differences, a couple links are below, the first gives a quick overview on the difference between the two, the second is from Fender, who is apparently still using all three finishes depending upon the product line.

Good link with that "Finishing School", thanks. I’d never understood why Fender lists some of their models as having a ”Urethane" finish.

Also, this was telling:

"The chief advantage of polyester is that it makes for a colorful and extremely tough, durable finish. Polyester guitar finishes age and weather especially well and are seemingly immune to climate and injury... Sonically, you get tones that are more purely those of the pickups rather than other elements of the instrument’s construction, which many players prefer."

Sounds like I’m more of a polyurethane guy if it comes to flavor of "poly". But, one could easily think too much about such stuff. I’m happy enough with all my keepers, among which I believe there are all three of those types of finishes (not sure which are polyester and which are polyurethane), plus one with barely any finish at all.
