Riveted Flap Brace and Devinyled wing skins - 3.5 hours

I riveted the flap brace onto the wings as I was on a roll with bucking AD4 rivets. Went quite quickly but getting the bucking bar into the root rib area was a bit tricky. I think i am going to enjoy riveting the wing skins....not.
 
Next I de-vinyled the wing skins. A time consuming process, but put on Netflix and the time passes easier.
