I forgot about the wing tips, because I had them loosely fastened on the on the wings in the wing rack tucked in the back of the hanger. I just happened by them and just looked at them in disbelief. Here I thought I was done with the dirty/dusty sanding, NOT! Oh, well, I finished them today and they too are ready for the first coat of primer. I also filled some more around the oil hatch door in the cowl, I decided the fit was just not good enough, and felt compelled to make it better. We shall see!
