My special has had a wiper slot in the top of the laminated screen for 25 years with no problems. It has an Ulster style frame with no top part. I did take some care in rounding and polishing the edges of the slot as well as the long edge to discourage cracks; I don't know if this makes a difference.
It has had 2 identical screens in that time - the first having been smashed by a stone.
