I started by using 2 part PU foam to create a basic shape for the wiper motor cover, making use of cardboard to retain the foam. I also used cable ties to mark the position of the motor so I knew when to stop cutting back when shaping the foam
Next I covered the foam I had shaped with body filler, followed by mold release wax and PVA release agent. Finally I laid down several layers of fibreglass. Then I after it cured I dug out the foam and filler to leave the fibreglass cover.
Trimmed, painted and fitted with a rubber strip to finish the edges and a couple of mounting brackets
