Do you mean you don't have bats flying around in your lab??Dang, dem der is some fish eyes. You’re more contaminated than a Chinese COVID lab.
That's got to be either contaminants in the air supply or maybe something wrong in the paint itself.. . . it’s on every square inch of this automobile. . .
If basecoat was too wet that would be giving you solvent pop, not fisheyes. If you said you tacked it well, my money is on the tacking. Was it a new tack rag by chance? My favorite tack rags are ones that are well-used. Not sure how you are tacking, but wad it up in a ball and just drag it across the panel. The only pressure of the rag on the panel should be its own weight. If you are folding it and wiping the panel down gently that way then you risk getting too much goo on the panel. I trust you probably already knew this given you've had really good results before.Tack cloth was a new Upole , I believe I do have some Crystal.
I never press hard on cloth , very light pressure.
Is it possible the basecoat was still to wet after 12 hours . One mistake , used Very Slow reducer in basecoat, garage temp 68 .
