I installed the rudder and was very pleased with the flush fit right off the bat. Contour was great after sanding the skim coat and applying the filler as needed. I also applied filler to the wing/tab intersection and have now brought the wing to the primer stage. I am sure low spots and pin holes will show up but they are very hard to find when the wing is multicolored like this. I need that black primer to show all! After church this morning, a major garage cleaning and prep will take place to get ready for another round of primer! Wing #2 coming right up....I'm just glad it isn't a biplane. :D
