I am thinking of making a cover for the front window on my 23.5 that will go on the outside of the boat. It will be sitting in broiling sun facing south. Will do sunbrella or similar. I am thinking to snap it on to the cabintop. I am wondering if I should screw the snap receptacles into the fiberglass or epoxy. I think they are generally screwed in as in the companionway cover. Has anyone made any such covers? Thanks
