Curious: Anyone spray SPI or other, outside in colder temperatures say, 0C/32F and above using infrared heater?
This is why I said IR infrared red heat. It heats the object (panel) not the air.Yes you can spray in those temperatures. Will the epoxy fail in those temperatures, yes.
That's absolutely a sound idea and I will experiment with this idea, however wind has no effect on metal objects. In other words, wind chill factor doesn't apply.If you are going to do it, test it on something small first. It would be kind of risky though. IF you were to try it, do only one panel at a time (unless you have a bank of IR heaters. Pre heat the RTS epoxy to 90-100 degrees Fahrenheit just before you spray. Get a handheld thermometer and see if the heater gets the panels get to 70 degrees. Try to fashion up something to keep the wind off of it as well.
You are correct in that wind will not drop the temp lower than the air temp, but if the air temp is 32, it would definitely need to be out of the wind to keep the metal temp up.That's absolutely a sound idea and I will experiment with this idea, however wind has no effect on metal objects.

When putting it in the sun, the panel temp. can rise quite high. So if 70 is ideal, what is the maximum temp?Remember too you need to keep the metal temp above 65 (min) - 70 (ideal) after you spray it for a minimum of 24 hours, otherwise it will not cure properly. If you can. putting it in the sun will help cure it and shorten the 24 hour window...
Higher than what the Sun will get it too. 120 is the recommended max baking temp. Barry himself recommends using the Sun, so it is not an issue.When putting it in the sun, the panel temp. can rise quite high. So if 70 is ideal, what is the maximum temp?
I've had dark cars reach nearly 140+. Retarder is my best friend then.Higher than what the Sun will get it too. 120 is the recommended max baking temp. Barry himself recommends using the Sun, so it is not an issue.
