Hmmm. Now that I am actually doing it, I suggest wiring the bezel to the roof using the predrilled cnc holes, not the CA glue. Wiring each side tightly is all that is needed and will get rid of the gap created by spring back when the hatch opening is cut out. Push the wires against the bezel sides and fillet over them and glass over soft fillets will be my approach. I don’t believe that lead weights on a board would be enough to bring the bezel sides into tight contact with the roof ,but I did not want weights in the way of glassing the bezel immediately after filleting.
