The patch technique I used yesterday turned out great. I found a couple of other places I though to add a bit of material. I am expecting that when I trim this back it will be nicely aligned with the rudder skin. I finished marking the rivet line, drilled and deburred. I countersunk the skin which I did not do any glass work on. (to let that hard cure) I then broke out the squeezer and squeezed as many rivets that were not involved in any of the glass work today. Next time I finish this up.
