I added small sections of blue and yellow foam around the gaps in the naca/fuse then laid up 1 ply of Carbon BID over the foam. I then spread Dry Micro over the BID. I took some Micro and filled the perimeter of the Duct/Firewall intersect as well. Not a bad job actually, but the West was setting up really fast. I had about a 7 minute window to spread it out. After cure, everything will be contoured down and I'll need to make my final decision on how to radius that Duct at the firewall.
