If you look up insulating paint on Wikipedia, the entry there
says all ceramic heat-reflective coatings are snake oil.
I did find a good discussion on Scientific American (https://www.scientificamerican.com/article/benefits-of-insulating-paint/).
They don't exactly describe it as snake oil, but they also suggest
that you not get your hopes up.
I suspect you can get your best results with a coat of reflective
white paint, and try to keep it clean.

Be interesting to do a bake off between this and the
plain “satellite white” I use.
I have always found it interesting that highly reflective
things like polished aluminum, chrome and silver paint seem
to be really bad at reflecting heat/sun. But we have all
grabbed a chrome wrench that has been left in the hot summer
sun and realized hot much it absorbs. I am guessing what we
see as reflective, Infra Red sees as flat black.

Which reminds me of this material that a friend clued me
in on.
You can get this at Home Depot (for example). It is
pricey; around $250 per 5 gallon bucket, AND it needs a
top coat of another material at near the same price.
However, for an advertised reduction in temperature of
over 60 degrees F, it may be worth a look.
