Today, it was time to prepare the rear fuselage floor. After removing the foil, we used a orbital sander with an attached scotch brite pad to prepare the surface. Once the surface is prepared on both sides, the inner side is cleaned and primed. The outer side will be painted at a later stage.
Once the primer dried, the longerons are fitted and attached to the skins with clecos.
Finally, the clecos are replaced by the blind rivets.
