Removed the masking from the interior around the doors that was used in spraying the light gray paint on the upper areas of the fuselage/cabin top.
Masked off the light gray painted areas in preparation for spraying the dark gray as touch up around the fuselage door openings.
Sprayed one small area of one door inside skin with light gray paint where it still needed some touch up. Then cleaned out the spray gun and sprayed the inside of the fuselage around the door openings with dark gray paint. Cleaned up and left the shop with the A/C running.
Returned to the shop 3 hours later and applied a second coat of dark gray paint to the areas around the doors.
