Eastwood epoxy in spray can, two part, sprayed in 85* sun, and three hours later I can poke my thumbnail into the paint. Does that sound correct? Doesn't this harden with chemical reaction?

 

Did you follow the instructions and press on the red button on the bottom of the can to release the hardner and then shake it realy well?

 

Yes, I did. And it is not hardening. I'll check it in the morning.

Maybe you can tell me of your experience, how quickly it dried for you.

*The following morning it is cured through. I can no longer poke a thumb nail into the primer. I called the guy at the auto paint store and he said that was normal, 16 hours to cure through.

 

I don't know about the spray cans, but using epoxy in a spray gun gives me an hour or two to dry,, then a few more to cure. I can usually paint over it within a couple hours, though I usually wait a day so I can sand.
