This thread has moved on a little from the original post, as I decided based on the advice given, to start over!
thought I'd better update this post for people hitting the thread for the first time.
Thanks.

OK, sorry to post with yet another mold related question but youtube has just confused me further, and the couple of books I have on moldmaking have also left me scratching my head.
I did post about this some time ago, but regarding a much smaller piece.
I'm making a love heart sweet, scaled up so it's about 9 inches diameter.
I'm working in polystyrene.
It's becoming annoying, everytime I sand back some filler, I dent another part, of ping off part of a letter.
Soooo... I thought, plaster would be more suitable to work with, and way better for the final piece.
But I'm not sure, can I just make a two part plaster mold of this? and if so, what release agent should I go for?
Silicone I assume will also work, but I'm looking for a cheaper way if possible, as the piece isn't finished yet, so really i just want this stage to change materials for me so it's easier to work.
Attached a photo of the piece, lots to do still. The back it the same as the front, but with no writing.
And yes, i know it's very cheesy! it's going to be a present for my GF if I ever finish it!
