A and C
While I agree with you, Pace is also correct - perceptions take time to change and people remain wary of severely damaged aircraft, boats or cars, perhaps not least because they don't understand just how good the repairs can be. That said I am also aware of some composite repairs to the structure of the undercarriage of DA42s that didn't go too well - who was a fault could be debatable, but it is still indicative that even in the aircraft industry there are no absolute guarantees. You will doubtless also be aware of the problems Corvalis had before being taken over by Cessna.
I think it is reasonable to say that working with composites and particularly some of the "newer" composites is highly complex requiring tight control of the layup environment, of the materials and of the techniques. Put simply, there is room for error.
