I had a K5 that my parents bought new and never took the top off. Of course I did as soon as they gave it to me when they were done with it. The seals protected the paint well, the only scars came from mishandling the top taking it on and off in a hurry with buddies that didn't care nearly as much as I did.

That was a half-cab top. They are fairly heavy and yours will of course be worse. Personally, I'd be more concerned about installing it before the paint has cured well enough, but it may not be a concern. I don't know, I've never heard anyone say if you should leave the top off X amount of time after a paint job. I'd certainly see what the painter thinks.
