Solar Reflectance:
Method: ASTM C1549,
Initial: .92
Aged: .87

Some folks like Bus Kote, but I can't find a published solar reflectance spec for it.

I know Marathon installs a roof paint that will improve the roof heat transfer, but their process include an inch of material under the paint is the same paint and process you posted?
