For a few minutes I stopped, looked at the project and thought to myself, "Is it REALLY ready for fill?" This is awesome! Well It's not ALL ready for fill, but in order to get a nice tight canopy seal, I need to add filler to both the longerons, canopy, and all other areas that 2 separate surfaces will come in contact with each other. I did my first round of Filler, sanded it down and am REALLY happy with it. the last round of filler will be right before priming and painting which is a ways off but nevertheless, this looks cool!
