Brief Description: Fuel tank stiffener sealing and riveting
First time working with Proseal. Applied proseal to both the stiffeners and the skin using my semco gun and a tongue depressor. Then I back riveted the stiffeners in place. I then used a fillet spoon to smooth out the squeeze out on each of the four corners of each stiffener. When all of the stiffeners were riveted in place I used the semco gun to put a dollup of sealant on the rivet shop heads.
