After the completion of the brushed crosscoat on the wings, I went back and ironed down any loose tape edges, then started the cleaning process. On the left wing, I picked and/or sanded the little dust contaminants away, then went back and wet the wing to give it a gloss finish. That showed me all the little specks I missed on the first round. The left wing is ready to start spraying, and I'll get the other wing ready tomorrow.
