Solvent pop or contamination

Activator bought new 2 weeks ago , Opened one week ago. Tack rag was new and wadded in ball , light pressure, everything like I’ve done it for the last 30 years. I am stumped , I have even painted with that propane torpedo heater for years. Not a good idea I know . Wiped the car down with a blue Scott paper towel that was new ,used many of them , just like in the past waterborne Wax grease remover and solvent grease remover SPI BRAND . Been using Scott paper towels blue for 30 years, no neighbors , my family too lazy to armor all Anything

The new tack rag would be the culprit I'd be most suspicious of. I've encountered this exact issue before when changing to a new tack rag. That was one of the only times I've ever had fish eyes.
 
The low tack tack clothes work well and don't transfer unless you are using them completely wrong. Surgical Blue are my favorites. Plenty of others out the as well. Gerson makes several.

The tack rag was new , but it was probably 7-8 years old. I still have it in the top of my trash can . Thinking about spraying a 3“ x 5“ metal index card with clear after I wipe it with that tack cloth ?? How can a tack cloth produce contamination?? There are literally thousands of contamination spots , probably 1/8 inch apart on every panel .
On the other side of the garage near my boat I have four batteries on trickle charge.
But they have been there for years.

Because it's the tacky shit from the tack rag that you just wiped on to the panel/base coat. That's why I don't use new tack rags; they transfer to the panel and paint doesn't like that.
 
The fact that it's on "every square inch" as you stated, in my opinion leads to air supply or paint application issues.

Did you try blowing compressed air through a clean white rag? If it ends up perfectly clean and dry, you can eliminate the air supply as the issue.
 
Very slow (895?) at that temp is something I have never attempted, so I can't even begin to say if the solvents would get out overnight or not.
 
i had a fish eye issue like this. would happen on every job and be on every square inch. took me a couple months to figure it out but it ended up being my mixing cups. i would mix primer and base in them and it wouldn't do it but as soon as i mixed clear in them it was fisheye city. if its not your cups then i would agree with some of the other guys that its something you wiped down with. could be the rag for the cleaners or the tack rag. from there i would say air supply or some type of contaminant floating around your shop. these type of issues are usually a pia to figure out.
