Fiberglass Dry time

It's been about 50* here all day and I tried to 'glass some rings in my door panel to install some mids. I glassed them aroun 10am and they still are not dry. The glass left over in the cup is plenty dry and hard but want I tried to glass is not. I went the paper mache route and dipped pieces of matt into cups of resin and smoother over the ring. Any ideas on why it isn't dry?

How come the leftover resin dried (1/4" thick) but not this?

Maybe didn't stir the hardener in well enough??

Try making a "hot" mix and coat over what isn't dry. That should dry it up fast.

yep what they said. resin to hardener ratio might be a lil off or just not mixed up enough

When I used to glass stuff, I added a HUGE amount of accelerator. Enough to make the resin hard in about 15-20min, if that. Once you have the basic shape of whatever you're glassing, go ahead and add lots of hardener to anything to glass.
