I've just done a couple of resin pulls of my bio sculpt using easy flow 120, my problem is getting the edges of the cheek areas and under the mouth to have enough thickness to them, especially as under the mouth is upside down when in the mould. I've spoken to mouldlife, they say use polyfibre or cabosil added to a mix and brush on after to strengthen the weak areas. I thought I would ask you guys that are more experienced than me if this casting problem is normal, or am I doing something basic wrong? (I did think of casting the bio in sections, such as face first, then the crown, but didn't know if the sections would bond well enough.) Any help would be greatly appreciated, cheers.
