The inside of the silicone mold showing fine detail. I have brushed out excess clay with a paintbrush and small strands of excess silicone with a scalpel.
The resulting inside of one half of the fibreglass jacket.
When removing the fibreglass, I used a hammer, chisel and wooden wedges. To ease with the removal of the fibreglass, much of the original sculpt inside fell out the bottom of the silicone as it was pulled apart.
Using an osculating soar, I have trimmed the edges of the fibreglass to fit along the marked parameters shown by the pen line. The edge of the fibreglass is neatened all around the head to allow better removal. The face area was then cut out to give a more even boarder all the way around.
Second side of the fibreglass jacket is applied and set.
After one half of the fibreglass has set, I was able to remove the clay wall and excess clay with a short bristled brush. The red marker pan shows where to build my second fibreglass wall up to around the parameters of the silicone. As the fibreglass did not fit right into some of the keys, I removed some with a chisel and plugged the others with clay. Once cleaned this side has been covered in gel coat, insuring that the fibreglass flange is also covered.
