It can be tempting to start that project in February, but glue temperature is EXTREMLY important to a good outcome.  Temperatures must be over 65 degrees for the entire time – from beginning to several days of dry time.  Your materials must also be over 65 degrees before you start.  Glue will not bond or evaporate properly in cold weather.  A heated shop (and time to leave the boat there)  is a must in the offseason.
