Last coat of paint !!.............. Few........
It's not a perfect finish but it should make a nice mould.
After pulling the plug out of the mould any blemishes will be little pips sticking up instead of being little hollows like in the core. These should be easily sanded off the surface of the mould with 800 grit paper if need be.
Here's a pic if the plugs with the top coat on. I'll let this harden for a week I think before I try to take a mould off them.
And here is the board that will for the part line of the mould. I've marked it out just by tracing roughly around the plug. Then I'm going to drill a hole through to get a saw blade in and cut out the shape.
I'm also going to fit a couple of Pins to the parting board to make sure that both halves of the mould line up spot on every time they are put together.
