I need some help solving my solvent pop issue with UV Clear with very slow activator. I've been spraying with this combination for about 3 years with great success.
Last week, for the first time ever, I started getting solvent pop, but only in the first coat. If I wet sand with 1500 to get all the bubbles and craters out then clear again, there is no solvent pop.
I've tried spraying over solvent base, water base, and even an unpainted speed shape, and the results are all the same, solvent pop only in the first coat. Every subsequent coat comes out fine.
I'm stumped, hoping someone can give me some insight, thanks!
