Brief Description: Rough up more tank parts for Pro-seal; z-bracket n
Used 120 grit paper on the palm sander to rough up the flanges of all of the tank ribs, stiffeners, nose reinforcement plates, etc. All of the surfaces (except for the rear tank baffles) are now roughened, and need to be cleaned before I plunge into the stinky stuff.
Also riveted the platenuts to 12 z-brackets (6 each side...the 7th z-bracket has no nutplates--the bolts go into nutplates on the spar web)
