I was wondering how can someone smooth out super sculpey before and how after it is cured. Any info would be greatly appreciated.

After its cured your only choice is very fine sandpaper and its a ball ache - sculpey doesnt like much intervention after its baked so most work needs to be done before its hard.

Yust to add, after baking and sanding you might want to polish it with nylon stocking-you can get really smooth surface.
However it is better to polish it before baking as Gaudin said...

The best result I have ever achieved on a baked model was to spray very gently and very lightly with grey primer that has been uber shaken and warmed up ( obviously it was licked clean pre baking )
and then after its fully dried - buff it with a felt pad - gets glassy finish, but it hasnt been 100% reliable - I may not have been reproducing the conditions right.

The primer then fills all the micropores and the finish is really nice, but if you overdo it you will get bold sculpey patches coming through

Thank you guys for the help. I ll try them out see what I get.I appreciate it.
