How long since the last coat?

Has it baked in the sun?

Does it still smell?

I think it has just not fully dried.

My test piece was done last summer and left in the sun during a heat wave. It is very hard.

My last coat was about a month ago. I can still smell the paint when it is in the sun. Not in the garage. I have no doubt my paint will harden just fine.
