Dale is just describing the normal process of laminating. One of the best sheet materials to use for your own flat mould is Formica, or a similar laminate. The gloss finish makes a very smooth mould, it is tough enough to be re-used indefinitely and there is little chance of the sticking problems likely with masonite - waxing the mould is still required, but it isn't too critcal.
The trick is to find someone with a large sheet of gloss laminate in a very unfashionable colour - as they will never sell it for its original use, the price can be right.
Of course if you are a slave to fashion, laminating on a uncool colour mould may be too much for you.....
