After curing overnight, the high-build primer was ready for sanding, which I took care of first thing, vacuuming and solvent-washing the cockpit afterwards.
High-build acts as a sort of sealer and final stage of surfacing, and as such highlights various areas requiring additional work, such as pinholes to be filled, and other minor interruptions. Because even the best efforts during the initial fairing and filling stages leave unseen flaws to be found after priming, I expected and planned for there to be an additional round of filling and surfacing work now, and later in the day I applied thin applications of an epoxy fine fairing compound from the paint system, filling pinholes, fine-tuning the shape of the corners and angles, places where the laminate weave was still showing through on the cockpit sole, and one small air void I uncovered at a corner of the icebox repair. I left the fairing compound to cure overnight in the overheated shop.
