It's quite possible to get the hard cab screen to seal if you do it right, but you have to do all this in sequence;
You need a solid screen which isn't way off shape / flat, with a good seal glued into it and the outside of the screen-to-seal joint sealed too. Whatever you use for mounting the glass in the screen should be completely watertight like mastic, none of that old rubber sheet stuff.
If you hold the completed screen on the truck you'll see a slight metal ridge all around the screen mounting area. You need to fit the screen so the seal outer edge sits exactly on that ridge, using spacers, washers, whatever. Sometimes you have to ease the mounting holes in one bit to get the fit perfect, especially if you are using a screen that was from another truck.
When you get that done, you need to tweak the 'in-out' fitting to get just the right compression on the rubber seal all the way round - typically it goes in too hard in the top corners and you have to push the screen 'out' the truck at the top to get it even when pulled in at the bottom by the military clamp or the civilian screw mechanism.
If you manage all that, and it is tricky, your screen will seal against pretty much anything you throw at it. I've tested Carryall screens in a downpour and got watertight fits on the screen, fabric roof, and even the window boxes.
