Removed some primer on the inside of the front skins around the perimeter of the NACA ducts and then scuffed the metal to provide a good surface for adhesion. Countersunk the fiberglass NACA ducts - I couldn't go as far as I would have liked due to the limited material particularly in the front areas. Applied some FlameMaster fuel tank sealant (mixed 20g + 2g = 22g including catalyst) around the perimeter of the NACA ducts and to the rivets as they were being installed. Riveted the ducts in place. I managed to scrape a bit of the primer behind the right duct on the outside of the skin, so lightly sanded that and will need to touch it up later.
