Step 11 Place the top pressing layer on the top sheet material. The top pressing sheet is something relatively thick and smooth that will not bond to epoxy. This prevents the bladder from pressing directly onto the top sheet and leaves a smooth finish. You can use a variety of plastics for this purpose. Just make sure that this layer is completely smooth
Go to tap plastics and get a sheet of plastic cut and use it. I started out using a thin sheet of metal however I also use a cat track system. I think it has been discussed within this forum also.
