Brief Description: Tank fitting/countersink prime/spar rivets
I dimpled the holes for the screws on the tanks and set them on the spar for one last fitting. I needed to trim back some of the proseal that was getting in the way of the two pieces, this took me ~20min per tank as I was being very carefull not to tug on the sealant any more than needed.
I then masked off the spars and sprayed primer down the series of countersunk holes as a corosion barrier.
The last thing I did was start riveting the ribs to the spars, 10 rivets, 2 ribs, not a big deal, but a big mental hurdle.
