Layed up 3 layers of 6oz fliberglass cloth for the headrest cover. Not my favorite material to work with, but I muddled through it. I used a pregreg technique where I laid down a sheet of 4 mil plastic sheet, then a piece of fiberglass cloth over that. I then squeegeed resin into the cloth. I cut out the shape of cloth I needed, including the plastic sheet underneath. I picked up his pre resined cloth/plastic and placed it on the headrest plug. After it was generally in place, I pealed off the plastic and then adapted the fiberglass cloth to the shape of the plug. Repeated for each layer. Worked quite well, despite me being five thumbed when it comes to fiberglass.
