As far as I know the design is different between the bus and the boeing which is why this is only affecting boeing planes. Someone mentioned that the paint shops were following boeing procedures/tooling - can anyone confirm that?
You're right that this may be maintenance companies looking for a quick $$$ but this is certainly something that all of us in the industry need to be aware of as people's lives are possibly at stake which will cost us all many $$$$$ across the industry if planes start breaking up.
