That's my thinking, too.
Just trying to find what's best, to get every reflective % possible,
both for PAR light and to minimize heat absorption into the surfaces.
Higher titanium dioxide %'s in formulation seems to be key, but then
there's also some nano tweaks being utilized by some to boost it, too.
Looking into roof top coatings, too. Some claim above 90%, as long as
kept clean.

Sure, there's silver, but that's none trivial for maintenance, although there are supposedly manufacturers that claim moisture resistance. Generally, engineering solutions try not to depend on a single component.

No, trying to achieve the "best" is a fool's errand, and certainly not an engineering imperative.

If interested, best commercially available product I've found so far...
Bright White
Solar Reflectance (ASTM C1549)
Initial .92
Aged .87
NASA has used some on exterior of Ares I-X Rocket, high reflectivity being primary reason.
If you know of anything better, that's readily available and reasonable, please let me know, thanks.
