So I've been wanting to add paint to all the amazing details on the Hearts of Steel figures. I feel like beauty of the molds are really left out and under appreciated and I'm going to do something about it. I would say I'm a fairly accomplished miniature painter from my Warhammer days but I'm worried about paint rubbing off of the figures. Does anyone have any good ideas on what to use? I was thinking maybe Gundam Markers would make it very easy but not sure how well it will stay on during a transformation. Any and all ideas are welcome.
