I etched the bottom skins and flap actuator parts to get them ready for priming.
I then alodined then antenna doubler plates. This was my first time using alodine. I think it worked? Parts are a light golden color.

I then attempted to alodine the sectiobs of the skin that overlaid with the doublers and didn’t have much success here. I think my mistake was that I let them dry after etching.
I did a bit more research and found some documentation from Aeroelectric that indicated that metal-to-metal contact around the antenna bolt holes is sufficient for ground contact so I decided to use that approach instead.

I cut painters tape using a quarter as a guide and masked off the bolt holes.

Another batch of parts ready for final assembly.
