primer issues. HELP !!!!

I agree with Cuudak, this looks like a hardener issue to me too... a lot of times they sit on the shelf for too long and you can have this issue... usually happens when you have already opened the can and left it for too long. Also with epoxy you really need to let it cure, epoxy is SLOW... let it set overnight for sure, then you can hit it with your filler primer. Check out the product sheet, the min flash time is probably 30... and the resand time is probably 72 hours.
