Wet laid up two plies of fiberglass/epoxy over the foam stiffeners on the RH wing tip upper IML. Ply #1 is 3 inches wide and #2 is 4 inches wide.
Laid peel ply over the flat portions of the layup. I didn't put it over the rounded parts of the stiffeners because I didn't want to cause resin ridges due to wrinkles in the peel ply.
