I wasnt happy with the proseal i did on the wing spar so today I took it apart and re sealed it. What a job. It still doesnt look like a pro did it but then again Im not a pro. As long as it doesnt leak im happy with it. Then my whole family (even G-Pa) helped me put the stringers on the wing skins. I made a jig to hold the stringers still under the skin while drilling.
