Poly-Fiber products for repairing some access panel holes that have worn out. This system is easy, fast and dependable. I have Poly-Fiber paint from 20 years ago that is still good. Cant go wrong with it.

I rebuilt a J-3 in my garage 40 years ago using the Polyfiber process. At the time, it was called Stitts Polyfiber after the inventor, Ray Stitts. It is a superior product. Other processes have come and gone since then. I no longer own that plane, but I know who does, and it’s still flying and it still shines like it did when I rebuilt it! If you are considering recovering an airplane yourself, buy the manual and read it through three times. Then, open it up and have it right there with you when you get started!

Pleasant nose with hints of citrus, good legs, with a bit of a bitter aftertaste.

I never did like the pink and with the untended. I can leave it clear or I can tint it with the polytone color I want.
