I got to work getting this job done tonight with putting on the duct tape for the bid to release from when cured. I started with 2 bid all the way round and then did a 3 bid lay-up on top to add mass. The ones that come from the factory for the side windows seam to have some thickness to them so I think the 5 bid will do, if not and to flimsy I will add more once out of the plane and to shape.
