Just a few weeks away from the first float of the season.
I got my repair kit out which has been stored in my unheated garage. I have not used any of the resin in the kit for 2 seasons. The containers were in vacuum heat sealed plastic bags. This winter we had 1 cold spell which was -10F and months below freezing. Both the resin and hardener are still liquid. No crystallization has taken place. I also have 2 small bottles of thick 5 minute epoxy. There are both usable also.
This seems really strange considering the same resin in my heated shop with lows of around 40 caused me all kind of trouble.
This stuff is hard to figure out.
