Well folks - I glued the inner and outer 3rd door skin on last night. I prepped everything according to the instructions, and put the panels on, using self tapping screws to keep things tight. After the glue is cured, I will pull the screws out and put more glue in the holes, trying to mimic the factory spot welds.
It would have been faster just to weld this stuff on, but I want to see how it holds up. Even though the parts that I glued aren't part of the inner structure, being the bottom of the door, they will get abused. It will be interesting to see how it holds up.
The factory spot welds were all rusting...
