Microspheres: Fillers filled with possibilities - CompositesWorld
Spray drying produces discrete, uniform hollow spheres in sizes ranging from 5 µm to 50 µm in diameter. Significantly, the use of phenolic resin, which is naturally fire resistant, provides fabricators a nonhalogenated flame-resistant filler with far less mass than other flame-retardant fillers, such as alumina trihydrate (ATH).

Is it one piece, or two with an internal bracing gusset?

I insulated the bare hood/bonnet of my retired Peugeot 106 with dense rubber foam, with aluminum coating. Reflects and insulates both heat and noise.

Here’s what my hood looks like. It’s thin barely metal with some holes and open cavities. No insulation or anything. How should I go about this?

That looks like a worst case. With some internal bracing you might fish sheets of insulation in the gap.
It looks loke the best bet might be to take the hood off, turn it over, pour expanding foam in the cavity and scrape off the excess,

IIRC that was done to a single-cylinder 250cc air-cooled motorcycle engine by Yamaha. And that's a really good engine.
