JND Studios: Indiana Jones and the Last Crusade - 1:3 Harrison Ford and Sean Connery

I think silicone needs to be painted with silicone mixed into paint as it only bonds to itself, that's what I've heard in the past at least
I also noticed the beard height issue, you would be able to paint it higher theoretically but I think how they do it is the hairs are sculpted going into the face so that a dark wash stays within them

Yes, I think they must definitely use a wash because the beard growth hair positions are exactly the same on the prototype as they are on the mass production statue (when you compare the hi-res photos of both).
