Quoted from uncivil_engineer:I bought the fuel over a year ago. It seems to act like naphtha. It evaporates very quickly and leaves no residue behind. What other options do we have in California?
So you don't *KNOW* if it was naptha or something else? Looks like Naptha has been banned in California for years: https://pinside.com/pinball/forum/topic/naptha-alternative.
What you need is something like Prepsol -- but if VOC containing solvents are illegal in California, you probably can't get this either.

Truthfully though, that doesn't look like traditional fish eyes to me. Those pits look really deep-- like maybe you overapplied the coat and had some air or water dropets trapped.
