Talc/epoxy can be thickened as stiff as you need and it sands better than anything I've ever used. I find there's no need to worry about the talc being hygroscopic as there is so much resin in the mix plus the top coats that any theoretical absorbency isn't a factor.

It's dirt cheap too if you get it from an industrial supplier. I paid $20 for a cement bag of the stuff 10 years ago - I still have lots.
thats what we have been using down here in el salvador...great cheap stuff and is nice to fair....we are using this method outside and to fair the insides of the cabin tops where they meet the deck as they had loose strand oem glass work
