Heat barrier experiment

So I've read through as many threads as I can find on lizard skin heat and sound barriers, and other products. Just helped my kid put kilmat down on the pan of his Vette. I'm building my Jeep FC, after taking some time off to heal. It won't have carpet in it, so I don't want to use a stick-on foil/butyl shield, or even Lizard Skin. I plan on color matching raptor liner inside the cab to the color outside. I considered spraying raptor over lizardskin, but...I don't know if that would be durable enough. I know that you can buy quality ceramic hollow spheres.

They aren't cheap. Web site says you can mix them with epoxy paints at about a quart to gallon. There are much cheaper glass ones available, but these are supposed to be strong and durable. I thought I'd spray a coat of spi epoxy primer over bare metal, then spray a coat of this mixed with epoxy primer, then top coat with raptor.
On the FC 150, a cab forward design, the engine is sitting right beside and behind you. There was a lot of heat generated by the little gas four, and the 2.5 liter turbodiesel I just installed isn't gonna be any cooler! I thought if I did this on BOTH sides of the engine and radiator compartment, and added kilmat on the Engine side of the compartment it might work. The raptor should hold up better over the epoxy than lizard skin. I'll make some test panels and see what happens. Anyone here put raptor over Lizardskin in a high traffic, no carpet area? Anyone mix ceramic with epoxy? I'm familiar with the practice of latex paint, but thats a big risk of product just to save a couple hundred bucks.
 
Years ago, when Valspar came out with a filling epoxy, I tested my epoxy with different types of microspheres and mixtures of talcs
All to any extreme weakened, the product to the point I said not happening.

I look at lizard skin and 3 or 4 coats the next day of epoxy for strength and call it a day.

Maybe someone has a better idea here, but this is my best guess.
