4/2/2015. There was a lot of raw fuzzy fiberglass on the inside of the doors. I used epoxy resin to coat these areas. Epoxy resin is extremely hard to sand. Continued work on the interior. In the background you can see the roll bar with the frame mount attached. One very odd thing about the doors. You can see in the photos that the bottom of the doors have indentations to accommodate spacers that are only on convertible doors. Coupe doors are smooth on the bottom. Are these coupe doors bonded to convertible insides? Could be. I filled the indentations in.
