Has anyone tried a ceramic paint
or some other coating on the roof of their FG camper? Nicely taped off and clean line edge of course. I know it would detract from the pretty shine, etc,etc. But helping to stay cool is the goal here. I want my A/c to take me down to 60 degrees.
I have looked at the statistics on the lab test results versus the claims and was not convinced that it would do all that much in the way of heat control. A white surface is nearly as effective. I don't think it will get you to 60 degrees. It would take lots of BTUs and the right kind of foam to get you that low.
Look at refrigerated delivery vans and trucks and then you will know what to do. Businesses that need the cooling ability have already invented a wheel that works.
Of course one of the big factors is you have windows
that gain heat. Cover them on the outside
with Reflectix when you are parked, it makes a HUGE difference in temperature. Glass acts like a heat sink that transfers that heat into the cool interior so you need to keep the sun off the glass. Putting the Reflectix on the interior is barely effective at heat control but putting it on the outside is very effective. You can test that for yourself.
