As described previously, filled mandrel nubs from the top side of the port wing, scrubbed surface with Scotchbrite & acetone, wiped residue with paint prep solvents. Lightly brushed the previously primed surface with Scotchbrite to remove several gnats stuck to the surface.
Used 5 oz of epoxy primer left from the previous day on the outboard end of the wing. Noticeably less viscous, the primer became tacky quickly after application. So tacky that bits of the foam on the end of the roller tore and had to be picked off the surface. Mixed and applied an additional 15 oz of Optiflow primer & activator to finish the first coat on the top and apply a second coat to the bottom.
