Here is another link re replacement of the cowl.

Cut and paste and remove the three extra spaces I inserted to beat the blocking.
You might also consider just taping a length of black 3M electrical tape full width of the cowl at the intersection of the top of the cowl plastic and the windscreen glass.
The strip of tape is effectively not noticeable and is a guaranteed seal at virtually no cost. For me, the tape seal lasted thru many winters and of course summers.
I think when it has a significant bow out in the cowl, a 3/4" wide elec tape is simply not going to hold that down against it's will to bow outward. However, I was considering an outdoor 3M double sided tape along the underside of the cowl, obviously applied with it off the vehicle, then pressed against the glass. You could trim that off with the black elec as you say.
The trouble being that when the next glass crack happens, it's a worse mess to separate the cowl from the old glass.
