Don't feel bad, like I said previously been using it for many years and it still sometimes bites me in the but. it takes a while to get the hang of the hardener. And yes on hot days it will kick much faster. keep up the great jobI had a rookie mistake using all metal. I mixed it exactly as the instructions said, and it cured within 30 seconds.

you can see here where it cured too quick. instructions said 3 minutes, but it was very hot and humid when i applied it. apparently temperature affects the cure time....who knew..ha!

I mixed in less hardener here and it spread good.

here I put less hardener in and when i started sanding it about 3 hours later, it was still gummy.
