Thanks Niro.
The door windows needed to be fitted now that the exterior of the doors were getting close to being fixed. A good amount of reshaping the openings including the corners was done. Since I didn't do anything to the openings until this point I was a little surprised at both how off one side was and how close the other was.
I tried not to rework the clear parts, but some extending was required on the bottom edges of both main sections and shaping on other sides. There were also a couple hairline fractures in those parts that had to be repaired too.
After I got the windows to fit I seamed the edges with 1000 grit sandpaper then started smoothing the faces with 1200.
