Cleaned and primed the horizontal stabilizer and vertical stabilizer skins. I also primed the VS internals and touched up the HS internals. The HS internals were my first attempt at priming and I wasn't satisfied with the results. I touched them up today and they look much better. Need some more practice priming. I'm still getting runs and thick spots.
The HS and VS are now ready to be riveted together. Once these sub-assemblies get riveted together, it might start looking like airplane parts!
