Thanks phrozin.
After reading your post, it dawned on me that there is a very good chance I sealed the Stra-Tele with shellac after the Timbermate and before I primed it. I can't 110% that is the case, as I have a mind like sieve.
I do use shellac
a lot because of its compatibility with practically everything you can put over it. It's my go-to sealer if I have any concerns about possible incompatibility.
So, the shellac may be the key to why I've not had any issues with the lacquer on that one. That finish would would have gone on around December 2018.
I think I'll make a note in my previous post referring here
