I just finished this project using VHB tape, Corning 795, and black paint on the inside edge. The windows look much faster – worth at least a half a knot.
I made a minor mistake in the length of a piece of tape being applied to the window cavity. Based on warnings that the tape never comes off, I was concerned that I wouldn’t be able to correct the mistake. However, I was able to remove and replace the piece of tape without issue – it just peeled off. My take-away is that the tape is not quite as permanent as everyone warns. I did read somewhere that the bond gets stronger over time, so this may be why it was easy to remove when I first applied it. Aside from removing old butyl, filling holes and sanding to create a flat surface, the only other prep work I did on the window cavity was vacuuming the dust and wiping the surface clean with a generous amount of acetone. This seemed to work fine.

I had fiberglass work done to clean up the window opening on the deck before putting the new windows on. I bought the windows from South Shore and am having them installed with 3M VHB tape, then Dow 795 caulking. The VHS tape adheres great to the windows, but not so well to the deck. There is 2 part epoxy primer on the window openings and it has been properly cleaned. A test area has been sanded and the tape doesn't appear to stick there much better. There is plenty of heat here in the North Carolina, so that is not the problem. Has anyone else had this issue of the tape not sticking well to the deck and possibly have suggestions that I can pass to the yard?
