Jim,
Putty tape seems to be the popular choice... easy to use, easy to clean up and easy to replace, if you ever need to pull the window frame for whatever reason.
RV stores carry it, I've seen it it grey and black.
If you cant find it, I'd opt for a closed cell double sided adheasive glazing tape. You could always just silicone it too, but it would require a cut out knife, should you ever decide or need to remove the frame.
