You may recall that when the airplane was brought back from PA, the
right winglet sustained some shipping damage.
To fix it, I had to grind the surface filler down to the fiberglass
and trim back the fiberglass. Then I had to cut out the foam.
Next, create a “plug” and bond it in place with epoxy/micro.
Then cover the entire area with two layers of UNI and the first coat of filler.
