As stated above, make sure that it is 65°+, or whatever your paint manufacturer recommends. I've only had epoxy primer have adhesion issues on time, and I sprayed it at 58°, with the intention of warming the shop back up right after spraying. I applied some Rage body filler onto the hood and about a week later I could see a small crack. I picked at it a little and the later of filler came right off, pulling all of the epoxy primer right off of the metal that had been sanded with 220 grit, IIRC. I was surprised. That days temperature was the only variable between how I've applied in the past. So, I am a stickler for the minimum temperature that manufacturers reccomend.

I've been very happy with Eastwood's epoxy primer. It's made by Kirker and rebranded for Eastwood. Aside from that isolated incident where I failed to follow simple direction, it has worked very well for me!
