now that you have the fish eyes, use a wax and grease remover and wipe down before you sand.
Sand it down past the fish eye (lube your sanding pad with w&g remover)
A few ways that they get there is grease on your hands. You need to use gloves when doing any final prep including the w&g remover prep.
clean all of your tools before you spray-should be a given but when i started out my first coat of base was slathered with compressor lube oil that came in my at the time HF paint gun.
Drain your tank, drain your moisture collector and purge the air line. all of these can have water and oil in them and it just makes for a bad scene.

I've been painting cars for a long time also and had my issues with fish eyes. In the 70's we would shoot a little fish eye eliminator in the paint and keep on going without knowing what really caused them. Of course we knew that silicone would cause them.
After I went to work in a local auto manufacturing plant as a touch up and repair tech, I got a real education on fish eyes or craters as the industry calls them. Auto manufacturing plants fight this type problem more often than you would think. Usually when we had a crater (fish eye) problem it could be traced back to some individual within the plant. Things that can cause fish eyes.......deodorant, women's powders, hand creams, perfumes, silicone contaminants from their personal cars (armour all on interiors transferring to clothing), certain cleaning solutions and the list goes on. We had a repair tech that came one day and every time he tried to shoot paint it would immediately crater. Turned out he had on a new uniform and the lab traced it to the thread in his uniform causing the problem. Apparently industrial sewing machines lubricate the thread as they sew. We lost almost a whole shifts production from one of our top coat booths due to an individual that had spent the day waxing his boat and came into work. When he walked into the booth the cars would break out with craters. He didn't have to touch anything. Had him take showers and new coveralls and it still didn't fix the problem.
This may be way too much information, but I would take a look at myself first to see if I have been around something that could be causing the contamination. Anything that may have been used in your shop, WD40, car pulled in with armour all on the tires, etc........and there's a good chance you may never figure out what caused them.

If I'm reading this correctly, is this the same panel, no fish eyes when you sprayed and they show up the next day? If so, that is solvent pop, not fish eye. Fisheye will show up immediately, you will see it before you are finished spraying.

Agreed, if it shows up immediately it came from above, if it shows up later it's coming from the underside.
Change primer, bondo or paint brands lately?? Get a different primer gun or sander recently??

+2. I was in the BS biz for 19 years. Spent most of that time as the painter. Never saw a fish eye that appeared after it was sprayed. To much clear to fast can certainly skin over and solvent pop as it dries though.
I know what solvent pop is this is craters fish eyes an the panel was stock nothing wrong with it just needed shiny again an I'm gonna try w&g before I start anything an when I cleared it was perfect an I left 20 mins later came back next day an they was in the clear idk last job it showed right after i cleared

What's the other variables in the equation?
Temp of the shop, heater running at the time or not, did you wet the floors or not, did you drain your compressor before hand or not, did you use wax and grease remover or not, what kind of cloth did you use to wipe it down, did you tack it off before shooting.
If everything looked good 20 minutes after you shut it down, I'd lean towards solvent pop. Or did you look at it that close when you were done shooting it?
