i called the company that makes marinetex about a question on curing temp and times.<br /><br />they told me that it will not cure below 50 deg.<br />at 55 it will take over a week.<br />at there optimum 72-78 it takes 24 hours.<br />it does not have to stay the optimum temp for the whole 24 hours. just keep track of time at optimum temp.<br />if outside they said to wrap in saran wrap or tarp to keep the heat in durring the night.<br />you can use a heater they said to keep it at least 4ft away from heat source.<br />they also said that the time to sand is when there is a blemish on top. (in 24 hrs at 72-78)<br /><br />just if anybody had the same questions i did.
