Actually, Boeing has already been thru this several times with different press releases, describing the process.
A 'bang' or contact with a foreign object that cannot be detected by a GVI is not a concern.
For minor damages detected by a GVI, an adhesive patch repair that takes a maximum of 1 hour to cure will see the airplane thru until the next C-chk.
At the next C-chk, or for major damages, a permanent repair scheme (similar to a traditional composite repair) has to be executed that takes about 24 hours, and is good for the life of the aircraft.
I'm just being lazy by not posting references, but anyone with access to the 787 SRM will be able to give references.
