I enlisted the help of my wife in installing the skylights. I used Cessna 1/2 inch wide green windscreen sealer and 6-32 inch machine screws and locknuts to secure the plexiglas to the roof, sandwiching the plastic with a metal flange. After securing the skylights, I backed the screws off 1/4 turn. Extrusion of the sealer required cleanup, which was easily undertaken using plastic Bondo spreaders and Mineral Spirits.
