I used some of the putty to stabilize the long screws I used. Here is where the screws work out nicely. The door was uneven with the outside of the fuse. I was able to adjust the screws out till the door was fairly parallel to the fuselage. This was a chance happening. I wish I could claim I thought about this in advance, but this technique really minimized the filler I would need to make the door flush with the fuselage.
