I'm using the 2.1 Production clear, and had a problem with tiny spots showing up over the entire panel. The spots are like tiny concave fish eyes, but not much bigger than a pin prick. Is this solvent pop? What do I do from here?
I was pushed for time, so I suspected I was going to have a problem. This was on a fiberglass panel of a motorhome. Here is the sequence of what I did:
Several weeks ago, I primed the panel with 2 coats SPI epoxy. Let it sit overnite, then sprayed a coat of Slick Sand. Today, sanded the Slick Sand to 320 dry, used SPI waterborn grease remover, then let it dry for 30 minutes. Outside temp was about 75 degrees. Reduced the epoxy primer about 15-20%, sprayed 1 wet heavy coat, let it sit about an hour and sprayed 3 coats of Chromabase metallic with about 10 minutes flash per coat, using medium basemaker reducer. The epoxy didn't feel totally hard prior to spraying the Chromabase, , so I suspect this is where I screwed up.
After about 30 minutes, sprayed two coats of unreduced 2.1 Production clear using the slow reducer, with 10 minutes flash between coats. The clear looked fine about an hour or two later. Went to dinner, came back a couple of hours later, and the pin pricks were all over the entire surface. What do I do now? Do I hit it with another coat tomorrow while the clear is still soft, or do I let the clear fully cure, and let solvent escape longer? If so, when should I re-coat?
Thanks for your help!
