We use the oracal flavor of the 6mil wall graphic vinyl for that. Found it has less tunneling issues than others when run on our QS UV printer. Need a suitable Permanent alternative at the moment.

Wrong material for the job.
Sorry to hear Bill, My little failure issues with the IJ35 vinyl is why i am no longer using it.
ij35 is great, That wall could very well be damp, or maybe cold air form outside?
or maybe have a leak causing condensation. Or maybe just the paint. Hard to tell unless on site.
The Material didn't fail in your case. You failed by using it for long term vehicle graphics, and expecting to last.
