After 3 layers of 2oz. cloth are used to give sufficient thickness, the edges are trimmed to final shape. I actually do this while the wax paper lined cardboard is still in place as it gives more control to the Dremel cutting wheel and protects the windshield areas from a potential oops with said cutting wheel if it grabs and digs. Next to the cowling you can see the beginning of the cockpit liner with the dashboard & driver body cut out earlier from the Phil Thomas epoxy cockpit. With this set up you simply slide the cockpit liner in from the back until it's fully seated & anchor it with a couple dabs of clear silicone on the back corners.
