Most of the nubs come off well but occasionally the playing would come off. The shoulders in particular have a spot where the problem is more conspicuous. The sprue nubs in general well designed so that you don't get that problem too much.
Also his arms come easily out of their sockets (which makes me feel like a wookie) so I may have to add a bit of glue.
I applied some oil paint to the sprue to see how the plating does with weathering and it seems to handle it well. Will post pictures next weekend of that process.
