I removed the clamps from the firewall and cleaned the excess epoxy. Also sanded the periphery to prepare for bottom ply. I cleaned the bottom with Gursel and finally epoxied the bottom ply in place. In the meanwhile, I realised there is a slight curvature fault with the port (left) side of the fuselage because of the door opening and corrected that while epoxying the bottom ply. I hope after exopy is set, the bottom curvature stays as I want it to be.
