I use Marbocote 227 as release agent, 5 layers to mold. Drying over night. Mix epoxy NM275 and brush it inside mold. Already cut fiberglass 280g applied in 4 layers. As final layer I used peel ply, and work out the epoxy with a rubber sweegee. Finally after cleaning up, I put a electrical heater inside cowling and installed top cowling, with clecos. To maintain the shape. About 30 degrees through the night and 45 degrees following day.
