As a follow-up, I have glued both my TF Cessna 182 and ElectriCub windshields - using no screws.  The canopy glue I used while invisible still is not completely transparent and aesthetically I know can be improved somehow I would think. Other than covering up the unsightly uneven glue beneath the plastic edge with a Monokote trim or something, perhaps there's a better glue to use?  Not sure.
