I don't know if epoxy is even capable of solvent pop.Sprayed 3 parts today they looked good as they were drying started to notice very fine almost like very fine sand in the epoxy doesn’t look like solvent pop but have never happened to me with epoxy before.
I get this all the time, maybe my activator is to old, I don't know but I usually sand it smoothSprayed 3 parts today they looked good as they were drying started to notice very fine almost like very fine sand in the epoxy doesn’t look like solvent pop but have never happened to me with epoxy before.
Interesting, I know that's not my problem though,Epoxy can do that if it's been exposed to below freezing temperatures for too long during storage.
Did you use waterborne wax and grease remover?I had the same thing happen this week spraying black. I'll try to get a picture of it next time. In my case I'm guessing its an operator error, maybe poor atomization? I might try using my Iwata 400 and see what happens.

Bare metal I use solvent. If I use waterborne I let it dry overnight with some air flowing over it, especially body filler….What are you using to clean before epoxy?

I use 125 micron strainers for sealer. Seems to have eliminated any concern about particles of any kind in the sealer.
