Some artists like to use a one-part professional silicone such as SAM-32 or Sil-Poxy for doll painting. Unlike traditional two-part platinum systems (like Psycho Paint), Sil-Poxy already contains its catalyst — it cures simply when exposed to air and adheres extremely well to cured silicone surfaces.
Advantages:

• Exceptionally strong adhesion — ideal for touch-ups, repairs, or fine details that need to stay put, or for dolls that will be handled a lot or perhaps in a less careful manner (such as a doll that might be used by a dementia patient or a child).
• No mixing required — quick and easy for small applications.

Drawbacks:

• Once cured, you cannot paint over it with standard platinum paints (such as Psycho Paint), as they won’t bond properly
• May end up more expensive if you paint the whole doll.

If you do choose to use SAM-32 or Sil-Poxy, always apply it sparingly and dilute it well with solvent, plan your layers carefully — it’s a wonderful adhesive and detail tool, and well worth experimenting with.  Although most artists only consider using it for areas of the doll that are problematic, or for fixing, some artists do use this silicone type successfully for painting the whole doll.
