I'm located in the north east and the temperature is already in the high 40s and low fifties. My boat is located in a unheated and uninsulated garage. I would like to do some Gel Coat repairs to it but i have a couple of questions. First question does gel coat cure properly when the temperature dips below 60 degrees? Question 2: If gel coat does not cure properly at low temperatures would it be unsafe to use a space heater to heat my garage while using the gel coat, would the fumes cause a fire?
