My suspicion is that if sawdust were used, a relatively coarse "grit" of sawdust would be best, as it would tend to fill with paint and level less than fine sawdust.I imagine very fine sawdust would tend to lie flatter, almost like the flakes in metallic paint.I'm thinking of the wide range of particle sizes I get in my shop--from the coarsest from my hand rip saws and my coarsest bandsaw blades, to the finest dust that I get with a router or a power sander fitted with fine grit sandpaper.

I also suspect that sawdust from hardwoods would work better than from softwoods, since the chips would be less likely to crumble or lay as flat as those from fir or pine.

Does anyone have any experience to report with choices of sawdust?

Lots of sawdust experience here. Softwoods create a tangle of shreds that tend to clog the plenum at the base of my tablesaw and often need prodding into the dust collector tube. I don't think that would be appropriate for flocking. Medium to softer hardwoods like Alder or Cherry produce a nice granular dust. I hate oak so no comment on that. Walnut also produces a nice dust, maybe a bit finer than the others mentioned.

How about a fine tumbling/polishing media like walnut shell? The problem with sawdust is unless you have a source, the only way to get it is cutting up stock, lol. Also, the amount of paint that it sucks up may add considerable weight; IDK, never tried it on a scope. I have laid a number of walnut shell non skid decks on yachts back in the day, and it took LOTS of paint.

I've always thought that as a substitute for sawdust, a finely ground coffee ground powder sprinkled onto a sticky substance, and then sprayed with a dull black coating would be best.
Have you tried that?

A better idea would be to employ "used" coffee grounds, dried up, of course. It would be a sin to not first drink whatever blend you prefer.

Think outside the box:

Darker would be smooth, gloss black surfaces -- angled so that all reflections get directed away from the optical path.
