Plating with Midas Green Gold Solution

Hello Community,

I am trying to make vermeil pieces and am having a bit of trouble. I
have casted my pieces in silver and then used the Midas Green Gold
plating solution to make my vermeil pieces, but the problem is that
the plating is not sticking quite well. Is it the solution i am
using or are most vermeil pieces made by electroforming. If
electroforming is the way to go are there any companies that do this
as a service.

Any help would be most appreciated.
v.s.
