Ok, I see that stuff, but it says, "The single-sided molding fits to the edge of your case or design, and a window is applied behind the cutout with VHB tape or sealant."
So is there more needed than just the molding? What's this "VHB tape or sealant" stuff? I though the molding just went over the case edge, then the window fit into the molding too, and that's it.
