You guys are gonna roll your eyes.
This is all squarely on my shoulders as a Newb/careless mistake.
It was a can of Rustoleum "Automotive Primer" that I had on my shelf. I finished the can and threw it away. Trash has come and taken it away so I can't evaluate it. It was not old, maybe 6 months on my shelf.
The base was a custom match/mix from Finishmaster that they put into a spray can for me. Again trash has gone and the can with the mix label was in it so I can't evaluate it. I didn't read the label close enough, either; just trusted the counter guy. Clear coat is a Smart brand high gloss can, also from Finishmaster, via their recommendation based on what they mixed for me for the base coat.
I am fairly certain I used the wrong primer. When I get back, I will spend more time and effort making sure all paint components are correct.
