primer issues. HELP !!!!

Could be numerous things. Most likely too much or bad hardener. Even with wet on wet systems I like to give the epoxy 24 hours, hit it with a maroon scotchbrite then shoot the filler primer. Just get your 180 out and take it back to the epoxy and respray after you pick up some fresh hardener. This stuff does have a shelf life too.

Don't over apply the product either. 50% overlap while spraying a 10 inch pattern and 10 inches away from the panel being sprayed. When its colder you need to extend the flash time nearly double.
