I refuse to get Fincecast DE models ever again, 45+ and all are broken from to little and cheap material. I''ve sent GW pictures and my really costly foam just for them and told them i'm boycoting fineCRAP.
I've been getting all finecast from 3rd party, i know its a grey area for ppl, but... just saying.
WITH THAT SAID, conversion ideas!
I would add greenstuff to them in tiny amounts (like a 0.5mm layer) and cut "U" shapes for scales, along withany DE Talos bits like the pipes and vials.
