Thank you everyone, the information here is great! I have thought about doing the whole job on my own in my garage. I have the equipment but not a clean environment like a paint booth to paint it in. My biggest concern is dust in the paint after it is sprayed if I spray it at home Does a paint booth guarantee paint free from dust? I'm hoping so. But I have not completely ruled out doing it at home yet as the painter is willing to help me as a teacher, consultant, as thus far.

Here's a question on what was said about the benefit of pre painting panels before assembly with regard to preserving overlaps from rusting. If the panels are sprayed in epoxy sealer before assembly, won't that give it protection from rust? Should I spray the area to be overlapped first?

Thanks again!
