This is a maintenance issue, not an aircraft issue. That is why there has been no disccussion of it.
The companies in question chose to use a substandard paintshop, and they have reaped what they sown.... The perils of contract maintenance. (not a slam on ALL contract maint, but the very real risks when costs become your number one prioirity)
Sooner or later someone will find an Airbus that visited that shop and it to will be a scratch...
A better title on the thread would most likely have drawn more comments and discussion as this is a maint issue, not an aircraft issue.
