Construction on the right tank continues, this time with sealant and riveting. The tank sealant (tank taffy) is pretty nasty stuff. I got the filler neck on, which was a good introduction to riveting with sealant in the mix. It makes everything more difficult.

I wound up being able to do two ribs in one batch of sealant. Three would be pushing it, with the sealant starting to harden, I believe. Vent line was installed. (Make sure to install your vent line clip with the neck–I’ve heard of people forgetting this.)
