There is a market for 1/4 scaled busts.
Hot Toys has made:
1)Rambo bust
2)Joker bust
3)Batman bust
4)Alien bust
5)Predator bust
and now
6)Iron Man Mark IV bust.
In all the examples above, they had 12" man-doll counterparts.
I think they are going for PVC construct on this 1/4 bust as it was for Hot Toys previous busts. So no soft vinyl, no soft painted silicone materials.....this should mean there would be no problems with the paint. Both my Hot Toys 1/4 Joker and Dark Knight busts are still looking like spanking brand new.
I'm getting this Mark IV, it's mine! I don't care!
It even lights up, not that this feature is important to me.
