Trying to remember how to paint from those basic body shop courses 15 years ago. I have this effect on some other parts too, but on those you can't feel anything at all, just looks more likely sparklies or small air bubbles just below the surface. I think I layered too much on without enough flash time because I was getting frustrated with the poor coverage I was getting. You can actually feel it on this part, like super fine raised specks.

We called it "solvent pop", and yeah, kinda looks like that.

You can likely color-sand that out, but polishing will be a bit of an adventure...

"Solvent Pop" was actually the term I was trying to remember, thanks.

So what causes it? Contaminants under the paint like oil or silicone?

No, not allowing enough time for the solvents to evaporate between coats. It's referred to as "flash time". Myself, I would strip it and start over but other more experienced painters may have a different opinion beer

I have some small area's of solvent pop on flat surfaces like my hood. Paint is about 4 years old. I've taken a bunch out with sanding and polishing but on that cap not likely.

It's solvent pop...
You'll be able to sand it out but by the time it's out completely you'll be into the basecoat.
It'll need re-basecoated and cleared. Pay attention to the temperature range of the reducer you're using
and give it more than enough flash time between base coats. A reducer that's too fast for the temperature can do that too
by skinning on the surface and trapping the solvent underneath.

Solvent pop for sure. Too much paint too fast, or not using a slow enough thinner. Contamination causes fish eyes.
