I managed to find some time to get the left fuel tank closed and finished last night, I am just about ready to move to the airport and fit the wings now. I used a tin of sealant on this tank and used a semkit on the right tank. The semkit maybe more expensive but there is less waste less clean up less mess and its so much easier to apply out the gun, no brainer!
Left tank closed and brakets fitted
Used the left over sealant to cover the rivets
Just a leak test to do then hopefully I can bolt it to the wing
