Thanks for the advice, next time I get into that situation I will shade the windows, there were several windows on the other side and I was using clear plastic. There were no doors or lights in the small area that I was working, only a window that would not open.
Iddee - PS. When my buddy finished the repair, the owner hired him to refinish the complete ceiling. He liked it better than the original finish.
Thats good, do you work that into your price and contract it out yourself or do you just recommend him? I try to do as little damage as possible, but don't care for the repair work, I'm no carpenter anyways. This wasn't bad because it was just replacing paneling and molding,
