This epoxy comes with what they call a tropical hardener. Because it is a tropical hardener it will dry very slow at tempatures below 75 degrees. If you do decide to use this at lower temps be prepared to wait 24 to 48 hours before being able to sand it. The plus side of a slow epoxy is it has plenty of time to penetrate wood giving you excellent bonding strength. Also giving you plenty of working time if you are trying to do a big lay-up of cloth and epoxy.
