Attached the five internal ribs. Used the syringes to put the sealant on the bottom of the ribs, cleco'ed them in place. Then added the sealant to the top of the ribs and inserted the cleco's from the front forward to put the ribs in place. I used what was left over to put fillets of sealant around each of the ribs.
I will let it cure for 24 hours and then start the riveting.
