The attached PDF had pretty good guidance. I would choose the thickest tape which can still fit under the windows. Maybe even double layers. I have a friend who used the 4941 series. After looking at the PDF it looks like the 5952 series has better adhesive qualities and possibly higher adhesion for the fiberglass and polycarbonate that we're using. The 5958FR has the highest PSI to thickness ratio. I suggest thicker to allow the tape to press into any irregularities. Thicker also allows for more differential expansion of the glass and frame.
As much as I like the VHB tape I still can't help but think to the auto industry. They use a urethane made by Sika for windshields. It has to be primed and heated. It cures in about an hour. I wonder if a combination of VHB tape and sika-flex might be smart. VHB to get a nice interior finish and sika for a permanent weatherproof bond and glazing.
