Today, I deburred the leading edge wing skin and then mounted two of the stringers, the bottom two. I countersunk them with a 120 degree #30 countersink from Avery Tools. I used RV-4412 rivets (Avex) after mating with EP-420 primer. I was quite happy with the outcome, but still have a few question about the use of Bondo for Darryl Murphy. Tomorrow, I hope to finish the four stringers on top.
