More vertical stabilizer work / Primer decision


Worked today some more on the vertical stabilizer. S. helped me this evening.  We got rest of the vertical stabilizer skeleton drilled, countersunk, deburred, scuffed and clean for primer.  We also started working on the VS skins with final drill and dimpling.

After debating in my mind whether to prime or not, I have decided to go ahead and at least prime the small parts and matting surfaces.  I may go ahead and prime the complete ribs and spars since it wouldn't take too much more work. I did not want to go through work and dangers of using an epoxy primer, so a self etching primer seemed a better fit for me. I was going to try and use SEM self-etch primer since some people seem to like the finish of it better, but couldn't find any locally.  Most of the builders around here that do prime seem to be using the NAPA 7220 Self etch primer and I was able to find it easily at the local NAPA store. I won't get to the priming until next week so we will see how it goes.  I will most likely switch to something else when we start the fuselage since it will have a better tendency to get scratched.

Hours: 3 hours
