I primed the wing parts in my garage. I put up plastic sheets and cornered of half the garage and used the wing jig and table to spray the parts. This was a big big pain. Once you spray on the first coat you need to come back and spray on another coat to get all the parts you missed. I did not spray the wing panels. I opted to spray paint the panels before I clecoed the panels onto the ribs. I bought spray paint cans instead of using a spray gun to prim the panel. Worked out OK.
