Autumn has definately arrived here along with colder temperatures. I
have a couple of gallons of polyester resin that I'd rather not move
into the house. It's in a plastic pail right now and the "scent" tends
to spread. I've tried putting the pail into a garbage bag but can
still smell it.

Would it be harmed if I just left it in the shed and the temperature
falls well below freezing? I'm hoping for enough nice days to finish
my hull but can't count on it.

Actually, storing it in a cool or cold place is one of the best things
you can do to preserve it. Styrene freezes at -31 C, so you will likely
be well above its freezing point. But even if it did freeze, it does
not swell when freezing, so there is no risk of bursting the container.

OK, styrene is only one of the components of polyester resin. It is
still true that cool/cold is good, and that it will not swell if it
should actually get below the freezing point.

I did not have any luck with storing polyester resin. I soon learned that
the resin has a shelf life.
When I purchased the 1 gallon I now have I did not know how long it stood on
the shelf before.
The first year I used about 1/4 of the gallon and stored the rest for the
following year at room temperature.
Then the following spring I used some of the resin and quickly found out
that it did not cured at all after several days.
I bought new resin and it did cured well. Now I have to dispose 1/2 gallon
of resin. Legally I cannot closed the gallon and put it in the garbage. I
was told that the resin has to solidified before it can be disposed. The
question is how am I going to solidify the un - curable resin already in the
gallon can?? Conversely I do not have problem with epoxy resin.

Have you tried to put some extra catalyst ("hardener") in the resin?

Which is logical. Polyester resin only needs a catalyst ("hardener") to
start to cure while with epoxy, the hardener is part of the chemical
reaction to form resin. So without the hardener, there will be no resin.

Dandy - that will make my wife happy. She never liked having the stuff
in the house. I'm just hoping for enough warm weather to get done with
the hull this season.

We have sheduled days that we can drop hazardous materials at the county
landfill. Maybe give them a call?

I haven't had much luck storing polyester more than 6 or 8 months. The
stuff I have had will start to polymerize on its own after that.

I've actually had a can of Canaidan Tire polyester resin sit in the
back of my fridge for 20+ years and then used it all up before buying
another can. I'd keep the resin aritight and cool. Wrap a wire tie
around the plastic bag and maby suck the air out of it for good
measure. I've heard that if it crystalizes it can be heated and used.

I've had good luck with refrigerating gelcoat, which is also a polyester
resin product, though it's been more like two years than twenty.
