Left fuel tank

Prepare, ProSeal and rivet left fuel tank.

The ProSeal fillet around the stringer was too wide and had to removed at the places where the ribs go:

Next I prepared the places where the ProSeal goes with sandpaper, SkotchBrite and cleaned everything, including the rivets with Acetone:

First layer of ProSeal, a thin bead on the skin and a thin bead goes on the ribs:

Like a taco flipped to the other side before going into the jig:

Alternating cleco’s and rivets too ensure the rivets fit:

Rivets in and cleaned with acetone:

Note that ribs 2, 3 and 4 have sealed rivets and the outside ribs the standard multigrip rivets!

In total this was one 6 oz ProSeal cartridge and many latex gloves to spread the ProSeal.
