JW was a master at anything he touched. Fiberglass, welding, plastics, motors, it did not matter.
That gelcoat was flaking off the wing, it just needed a little encouragement. The pin holes were filled before the poly paint and sanding.
The finish is factory perfect, actually better than factory. There are YouTube videos of the glider after the work was completed.

It is a joy to fly.
You will also find videos of Jim flying his beloved Speed Astir, "UF", hence the Uncle Fuzzy monicker.
Jim is surely missed.
