Getting a "Pro" to shoot the last stages of a PU refinish is an
excellent idea BUT be 100% sure your "Pro" has experience painting
large objects. Most bodyshops paint small objects like quarter panels
and hoods. Painting something as large as a wing or as convoluted as
a fuselage is a whole different animal. Keeping a "wet edge" to the
paint is an art on such objects.

How do I know? We contracted out an AS-K21 wing Imron (isocyanate
catalyzed) paint job to the local high quality body guy with his world-
class spray booth and equipment and got back a finish that we had to
sand completely off and redo. I shot it the second time with
inadequate breathing gear and got a great finish and felt like crap
for 2 weeks.

Ah, the good old days!
