Claim 1: “by putting on a lighter coating, it can reduce the temperatures by about 20°”
DISPUTED
The evidence provides conflicting numbers for temperature reduction. One source mentions 10°F, another 10 to 16°F, and a research review mentions 23.7 °C (which is approx 42°F). The claim of 'about 20°' is not consistently supported across the provided evidence.
