Is this stuff made for modelling or is it made for gap filling?
It was originally made for fine, white porcelain repairs. Here's the company's
own page about it.
I agree with most of Doomhammer's post. As the name suggests it's a
lot finer and smoother than milliput standard yellow-grey. This means it's less 'crumbly' and a bit less messy than yellow-grey, and it cures much harder too. (Which is something because y-g cures pretty hard! I once mixed up a half-inch thick piece of superfine white to break up for basing rubble - I could only break it by bringing it outside, setting it on a stone, and whacking it several times, very hard, with a hammer!)
Freshly mixed superfine white is also a bit firmer, which can be an advantage at times and feel like a disadvantage at others, and to be honest the bright white colour is not the best when you're trying to model small details with the stuff. Gives you a kind of snow blindness! But don't let that put you off it if you want to try it. Like any other sculpting medium you need to get used to it, and if you want something that can be sculpted or sanded
very smooth, that'll do you. And maybe mix something else in it to tone down the white.
For more about it, look at Miliput's superfine white
case studies, particularly Luca Zampriolo's mechs. He used a mix of milliput superfine white and milliput black to create a light grey putty for sculpting.
IIRC Bob Naismith (sculptor of the original space marines, and many other minis from
GW and elsewhere) uses superfine white for sculpting vehicles and some other mechanical parts.
