One last feature. The two cans containing the two parts each have some velcro attached so you can keep the two containers together.
      With some sealant mixed it was time to start riveting stuff to the skins.  You start by back riveting the 11 stiffeners. I used my usual technique except I applied a dollop of sealant to each rivet hole and inserted the rivet. Then before applying tape over the rivets, I cleaned off the excess. Next I put a layer of sealant on the faying surface of the stiffener and put it in place. I also used my mixing sticks to burnish the upper surface of the stiffener to squeeze out the excess sealant.
