Went over the sanding primer on both skirts with fine sandpaper. Feathered the fillet I extended on the right skirt. Shot it with sanding primer—darn, too heavy—got a run. Several hours later the primer was dry so I sanded out the run and shot it again. After this dried, I shot both skirts with NAPA primer. After this dried, I clecoed the skirts back to the frame. The finish turned out quite acceptable. Next up is to join the skirts together and glass the aft end.
