GRP in the examples illustrated are produced by carving polyurethane sheets into the desired design – painting the finished design in liquid wax to prevent interaction between the polyurethane base and the polyester resin used to laminate the glass fibre sheets.
All examples were produced without a female mould, thus the design was produced back to front.
It is possible to execute work on a large or small scale, an example of an intricate design is the polished bronze GRP plaque depicting the London to Brighton Vintage Car Rally.
