Dave - store the glue in one of the foam boxes used to keep ice & beer &
pop cool on a summer picnic.... or wrap in a blanket?

Dave, I can't do that wrote:
Thanks guys, mostly I just want the stuff to not freeze overnight. It is warm enough in the garage when working out there as I don't go out until after midday and it has warmed up enough to work.

So far the applied glue must be drying enough before it gets too cold out there as it is holding well. My guess is that the garage does not drop to around freezing until around midnight.

I bought an inside/outside wireless thermometer but it only worked for two days so I am still not sure when and what temps it gets down to. The glue instructions say allow 1 to 3-hours to set so it seems to be working OK at the the temps.

I was hoping to make something a little more bespoke and compact rather than a frypan or crockpot, but thanks for the thoughts. I will cruise the junk shoppes and see what I can find that might be better.
