This is the vacuum formed visor using the buck that the crescent Cs showed up on. I’m not sure if the visors tend to get clearer than this or if I did something wrong.
Ok. Now I'm with ya. I had to back up a page and catch up.
The Cs are grinding from the electric sander on a coarse grit.
So the "resin or bondo layer" comment was in respect to the buck. Gotcha.
So... you didn't coat or smooth the buck at all since those earlier photos, is what I'm getting looking at the video.
The still photo looks like there's visible "pillowing" in the buck. It looks like you can see where you sanded some of the high spots (the hills), but they aren't even with the valleys.
If I had to guess by those photos... To me it looks like a wavy buck resulted in a wavy pull. The blinds in the window have almost the same grid pillowing distortion as seen on the buck.
If it were me... I'd work to smooth out that buck. If resin is an option I'd probably use a black resin and then sand that to a glossy finish. Let the gloss of the resin be your guide as to how smooth the pull will be. I mean... an extra hour of sanding beats wasted hour and material on the pull, right? At the very least a beautiful smooth buck takes one variable out of the equation.
