Brief Description: Prep , dimple and prime left rear spar
Prepped (scotch brite and acetone) spar. Double checked and reamed out (#40) flange holes above W907B / C. Did bottom holes first and dimpled 67 holes before realizing that it was wrong. Turned over, reamed and dimpled top holes. Primed aft side of spar, going to let dry 1 hr and then do front side. Giving primer time to cure. found two small areas and re-primed them. Letting sit until I prep the right spar.
