Would it really not add strength, I would think the opposite.

Yes it would be tough to sand

What for? Diatomaceous earth would make it heavy and harder to sand
without
adding any real strength.

How about diatomaceous earth as a filler.
It is the skeletons made of silica of microscopic creatures from long
ago.
Has anyone tried this as a filler? I would think it would be good and
cheap.

I need to fair large deck surfaces in prep for paint. The repair thus

has been all polyester, can I use microballons to create a polyester
fairing compound?
