Today I received the missing parts from Vans, so I was able to finish those sections and test fit the vertical stabilizer together for the first time.
One thing that I noticed is that it was rather hard getting the holes in the skin to match up with the holes in the center nose rib. Had to joggle things around a little. Eventually it all fell into place.
Time to get the primer items all straightened out. Need to order a mini-HVLP spray gun and run to Sherwin Williams.
