Took quite a few coats of clear to get it smooth and nice- problem being that every time it got glossy there was another little flaw in the surface to contend with. Ended up filling the flaws with some HEAVY coats of clear and then doing a good thick coat over the whole thing.
Then i blocked it down with 2000 grit and am pretty happy with how flat the face turned out (though there is much room for improvement, its not noticeable).
I then rubbed some wax into it to reduce the matt finish to more of a satin finish- i really like the way it looks but may buff and polish it later (never will do this)
So yeah, all finished as far as i'm concerned. Just need some small stainless dome head screws and nuts to secure it to the mask.
(Looking at the close up, actually could use some more sanding with 2000grit, but meh)
