Dunno about urethane but polyester can check and even crack. I've got a '78 Tele Thinline with crazy checking patterns to prove it!

OK you got my curiosity up...are you sure it's not one because it's a polyester base with a nitro topcoat?Dunno about urethane but polyester can check and even crack. I've got a '78 Tele Thinline with crazy checking patterns to prove it!

Found this statement with somebody who seems to have some pretty strong creds, from post #2, here:
https://www.tdpri.com/threads/anyone-know-when-fender-started-using-poly.71927/
"I'd like to make one thing clear... ALL FENDER GUITARS PRODUCED AFTER 1968 HAD A POLYESTER UNDERCOAT WITH A LACQUER TOPCOAT!!! There is no specific ratio. Enough poly was, and is sprayed to properly fill the grain while preventing a burn through while sanding."
:friendly_wink:
I guess this could be right…just assumed the finish was all poly based on various books & articles stating this. S'pose I could actually test once I haul the Thinline out of storage. (I store most of my fav guitars when I'm traveling a lot, but do keep some of 'em at home throughout the winter due to better humidity control.)

But the point is that the level of humidity should medium all the time, not more than 50%.
