I’ve been waiting to do the final door gaps until I had the doors and cabin top flush with each other. And I wasn’t able to make everything flush until I was done with the window surrounds, as they build up the cabin top just a bit.
Now that the doors and cabin top are flush, I began the final gapping of the doors. All the gaps are tighter than what I want the final product to be (which according to one of the guys I’m considering as a painter should be a little thicker than a credit card). To get to that gap, I stuck some 80 grit sand paper to a stiff putty knife and started working along the gap. That gives me a nice consistent gap that’s pretty close to where I want it.
