Brief Description: Encapsulate shop heads with Proseal, rivet Tanks R
18-5: Encapsulated all rivets so far with Proseal at this time which included the stiffeners for both tanks and the two flanges on each wing tank. Step 6: Remembered I needed to rivet the Aft Inboard Tank Rib Sub-Assemblies for both tanks so did this using the pneumatic rivet squeezer and encapulsated both sides of the rivets. Have not riveted the five nutplates in place yet as they will not require sealant. I was at the end of a batch and had just enough to encapsulate the rivets. Tank ribs next.
