Stiffeners for left tank

Tonight was a pretty quick use of Proseal for the left fuel tank. This time after I mixed it, I put it into a zip lock bag that we use to ship parts and trimmed a small piece of the corner out of it and used this to apply the sealant instead of the popsicle stick. It wasn't perfect, but it was cleaner than the stick, so I think this will be my preferred method from now on since I have plenty of bags! After applying the Proseal, I shot the rivets, cleaned the edges, sealed the shop heads of the rivets and called it a night!
