Between the Z grip small fills and large area micro spreads, this bird is begging for primer. I spot filled the low spots I could find with Z-grip first thing, then while they cured tackled the nose gear strut fairing and sumps. I went with the slow hardener knowing she would sit all night curing. I then sanded down the gear leg fairing micro to a good preliminary contour. While working on the left main gear leg, I looked over my relief tube exit and decided to make a change. In flight at cruise speed, the relief tube (pee tube) works, but just barely. Knowing a little more suction would help, I contoured down the forward section of the exit, to create a lower pressure zone behind the exit. Now all I need is a 32oz pot of coffee before takeoff :)
