Sanded down the slurry coat on the inside of the cabin top. After drying, I applied another thin coat of slurry. Sanded once again. There was only on spot aft of the right door that needed a bit more fill. I wet out two layers of glass to use as a cover for on the forward switch panel in order to cover the front support tube. I cut a card template that I'll use to later cut the fiberglass sheet.
