I think one trick to that working is using a very thick coat of the paint. It needs to be thick enough to scatter light like using the same properties as snow. A thick coating like that all over your skin would probable block sweating and create a dangerous health issue.
I wonder. He did need the snow-scattering effect to get the barium-based pigment to work, but it seems like the dense packing achieved by the varied sizes of nanoparticles might suffice for light rejection without that effect. It didn't sound like he re-tested that with the new recipe.
Tech Ingredients also covered cooling paint and referenced the NightHawkInLight Video but they went into a bit more on application. It still needed a thick coat. https://youtu.be/dNs_kNilSjk
It's been a while since I watched that one. I'll have to give it another look. They were also using the barium pigment, but I can't remember if they used the multiple sizes of nanospheres.
