Entire wing heat shrunk and cleaned up,apply 1st coat of Poly Brush.After allowing to dry all the lexan access ring reinforcements glued in place.Rib stitching.........What a job $#@!anyhow went down that road ,I actually stitched around each individual 1/2" rib tube top and bottom using the regular hidden seane knot method,I acheived this by using a bent needle to run the cord and a looped peice of 32 thou lock wire that had a loop formed on the end of it to catch the cord and run it around the rib and back out the hole.....Good news ,nice job Bad news one wing to go .........
