Tonite I cleaned and roughed up all the stiffners, filler neck and drain flange. I fay sealed the stiffners and will rivet them tomorrow evening. I riveted the filler neck and drain flange and with the sealer I had left, I sealed the access plate on the left tank. Now it's ready for leak testing. I'm keeping my fingers crossed for that. I'll probably not leak test it until the weekend. Hopefully, tomorrow evening Reva will be able to help me seal the ribs in this tank. I'm really ready to have the tanks done.
