Pigmented or Metal Filled Glass Reinforced Plastic
(1960-72)
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.
