Poll for Those with Paint Blistering / Bubbling Defect

[Man.v.Cars]

I have read all the 35 pages of this. I’ve also looked at the poll. Still feel none the wiser. It doesn’t appear that ‘every’ Emira has or will suffer from this issue. That would indicate the problem isn’t universal- it’s not every set of doors or all panels on all cars.
That said, it’s likely many cars aren’t dailies. As such, they perhaps don’t see rain. But, they must get washed. So- why are some cars suffering and not others?
I have an early car built around the same time as Harry Metcalfes. It’s done 7k which I’d consider high for an Emira. No blisters. Yet reading this thread would have me thinking the doors should look like bubble wrap. What is the common denominator?

My thoughts are that the treatment applied may not have been applied evenly on the panels. When you look where the blistering occurs it seems to be in the same places, top and bottom of the door, around door handles and under the mirrors. Mine have gone in those places and replicate pictures of others.

Batches where the applied coating was running low before being topped up? I doubt we will ever know the truth as it would involve admitting liability, even though it's clear it is an at source manufacturing fault.
