More sanding today on the cabin interior. Because I am doing some finer touch up work, I switched to "putty flex" filler from Aircraft Spruce. You use very small quantities and it sets in 6 minutes....letting me sand in 20. While the right side was curing I started to layout and rough in the headliner on the left side. At the end of the day, I have the left side headliner cut and ready to cover with headliner material. Tomorrow, I will start the day by, sanding a little more and then cut in the right side overhead liner.
