    Why not just put the reflective side facing down, and leave it be? 
That's what my father-in-law and I did ( two garages ).  Looks fine for a 
garage ceiling, and even helps with lighting a little.  Throw some 
aluminum tape on the seams and call it done.

    Painting it sounds like a right bitch, to be honest.
