We noticed an about 2" crack in the fuselage outer skin layer after we moved to our hangar E8 at KOFP. We have no idea what caused it. Stratford consulted with Zach Chase. Then he ground out the damaged top layer of glass stopping at the foam and then epoxied in 4 layers of glass. The final steps were he applied putty and sanded smooth. He used West System epoxy for the job. Hooray for fiberglass!
