Got Kay to help me with the first round of rib sealing. She did the bucking while I manned the gun. Not sure if this was the best way to work. I avoided smiley faces in the skin, but Kay had a hard time holding the buck bar on the center of the rivet. She stressed her one knuckle pretty badly as well. The sealant is a mess to use and clean up. The MEK is nasty to be around. Had sufficient exhaust capability, but I still got overexposed. Finshed the right tank and started the left tank. Plan to finish the internal ribs on the left tank tomorrow night while Kay is still in the mood. Kay 6.0 hours
