Installed foam ribs using Flamemaster sealant. There were 2 on the left elevator and 6 on the right to install. No issues using the sealant. I used a 6 oz tube and a caulking gun. Since the tube diameter is smaller than the caulking gun I used a socket with an extension to push the sealant out. This worked well. Once they were all set, I peeled the backing off of the previously installed 2 sided tape on the TE and clecoed the TEs. It will now set for a couple days before riveting.
