This can be quite an aggrevating process. I needed to do one more go on the bottom side to minimize some creases that I had caused yesterday with the iron. I accomplished that, but then after removing the weights, there was a slight anhedral again. Sooo, I heated up both sides with the heat gun (not as much as I would if removing wrinkles)... that significantly decreased the anhedral (after being under weights while cooling)... and now there seems to be a very very slight inverse camber again... very slight though... uhg.

I'll leave it under the weights over night.

It's basically like you have to keep doing this until you happen to get no bowing, then quit while you're ahead. But it's so slight now that maybe it's fine. The very slight anhedral might make leveling the horizontal stab a little harder, but... whatever. I guess I'll just have to keep at it.
