Glass pinchweld

[Mike_The_Grad]

Hey everyone, I recently tackled the rust issue I had around the rear window glass pinchweld and gasket area on my 72 c10. I had to cut out all the rusted areas and fabricate my own patch pieces. It wasnt fun and took me an entire weekend to get it all welded in. Im happy with how the areas I patched will look when the glass and gasket are installed. But my question is, how important is it that the pinchweld area itself is smooth and flat where the gasket is installed around the back glass frame? I ask because it was proving rather complex to find patch pieces that marched the offset lip of the pinchweld area around rhe back glass. So I tried to simplify the work by only cutting out the area that was rusted and leaving the factory spot weld pinchweld intact and using sheetmetal with a 90° press bend to fill in the missing pieces. Ill include some pictures for clarity. Because my welds in this area are not completely super flat. Im worried about having leaks when I reinstall the glass and new gasket. I've already got a ton of time invested in the repair and seriously trying to get to the next step in sanding and epoxy priming the outside cab so I can apply my 2 part drip rail sealant and get the cab fully sealed before the rainy season starts here in Southern ca. I dont have a covered area to store the truck while I work on it. And these short winter days are killing my work time with usable daylight hours. Thanks for any input.

And yes I see the pinholes I need to go back and weld up. Im only asking about the area the gasket is supposed to seal against for the back glass window.
