I envy you guys with no pinholes to fill. My cowl (green glass) resembled a window screen in spots. The inside was actually less porous than the exterior, though I can't say the same for the texture. Took two applications of epoxy to kill almost all of the holes.

I squeegeed a portion of the inside of the cowl each time I had a little epoxy resin left over from another task. Most of it was coated while glassing in the windscreen. Thinking about a coat of paint for the interior but not convinced that the pros outweigh the conns. It's sealed, and that was my primary concern.

One of the "pros" is that a coat of white paint would make it brighter in there and easier to inspect stuff and look for leaks.

Nice hard shell coating. Good visibility of any drips/leaks. Easy to wipe clean with some soapy solution.
This is before laying down the reflective aluminum and heat shielding from Van's.
I'm doing mine this way!

I also use west systems epoxy to close and seal the cowling.
After that, I paint on a couple coats of Diamond Brite aluminum paint.
It creates a nice oil and fuel proof surface and since it has a high aluminum pigment content, it also acts as a heat shield.
On my last RV8, I didnít install the foil heat shield and saw no adverse effects due to heat inside the cowling.
YMMV

Just finish it like the outside...seal, prime, paint. Maximum adhesion of the reflective aluminum foil depends on surface quality.
