I had a big day of priming yesterday. I got both flap skins primed as well as both left wing top skins. I also was able to prep and prime the flap braces. No pics, but you will see them all soon enough.
I also started riveting on the Aileron Attach Brackets to the right wing and noticed something. When fitting the flap brace after the top skin is on, you end up having to shoot the rivets when they could have easily been squeezed if the skins weren't on. So on the left wing I:
Mounted the Flap Brace prior to riveting the top skin.
This allows for squeezing and doesn't interfere with anything since it is logically the next step after riveting the skin anyway. Note that I am not going to mount the attach brackets or aileron gap faring until after the skin is riveted.
