I rigged up a double boiler arrangement (pan full of water with some junk on
the bottom to keep the epoxy jug up a little). Put the thing on a gas
burner and get the water hot. I think you're looking for 180 degrees F in
the epoxy, but I just quit when the epoxy was shiny and clear again. Works
for making the old ketchup pumps work again too.

I've heard of others who just put the epoxy jugs in a car, parked in the sun
with the windows closed.

"That's an old trick."
What's the other trick if the epoxy resin has been on the shelf too long,
may have frozen and shows various sizes of lumps.
Some people will simply dispose of it. Other people I was told will warm
up the resin and use it as new.
Maybe someone can tell us how to warm up the resin and to what
temperature?.

Ever mix up that $100 a gallon sucker syrup and end up with extra in
the bottom of your plastic milk jug? Just for grins and because I'm
stubborn and cheap I stuck it in the freezer, ate lunch, went to town,
drove home, took a nap then pulled it out in the interests of science.
Rock solid. 10 minutes later, soft- roughly the same stage it was at-
only 3 hours later. It seems to have adhered and set up normally. This
was a deep freeze, not my refrigerator icebox. Also, I had used
sawdust for filler if that makes a difference.

That's an old trick. Sometimes, the epoxy will still be usable a day or
so later but it won't prevent it from curing indefinitely.
