Window Questions -Late 50s Hehr Windows

I am working on restoring the windows of a 59 Shasta Airflyte. I feel pretty confident with what and how they need to be redone. (Thank You Mobiltech). However, I don't have a lot of confidence with the window frame keeping the water from getting in behind the skins and in the walls. A little help understanding this would be appreciated.


In this paragraph I would like to refer to the Standard Awning Hehr Window. I have included a pic or two to help with the explanation. I realize these windows have two gaskets; one that slides onto the metal once the glass is set into place and that it pushes up against the window to help seal out the elements and that the window stays will hold the window in place. The second gasket (back gasket) that seals the awning window when in the shut position. However, I feel that I need to use some gutter seal or something similar either along the edges of the glass after it is set in the frame or maybe add a fine bead of gutter seal along the frame edges prior to setting the glass. That way the glass will have a seal that will help keep the elements from seeping behind the frame. I would also add a small bead of gutter seal to the corners of the back frame as well. Am I over doing my thoughts on this or even thinking it out properly?


Large Front Window frame corners - The front frame window corners were not welded from the factory line so there is play in the frame at the corners. I realize that when the frame is screwed into place that this play will not be there, however, the crack at each corner will still be there. I thought that some gutter seal on those corners from the backside prior to installing would help seal the elements from getting through. Any thoughts here as well?

P.S. These are pics before cleaning and polishing.
