Exactly the same procedure is followed in preparing the finished moulding shown in Figure 27:3. The former-mould is treated with emulsion wax, wax polish and PVA release agent, then a single gel coat followed by the requisite thickness of glass mat (minimum two layers) and resin. After curing the mould is released, washed with soapy water and trimmed to exact size; it should not require any further polishing.
The method described above gives a smooth surface on one side only, marked (A) on the drawings, as the undersides will have been formed by the roller. They can be ground off smooth if necessary but will show the cut ends of the glass fibres and should be painted or otherwise protected.
