"Of course it is theoretically a paint adhesion problem that is what blistering is but it is not caused by a problem with the paint or primer."
As I stated, not a paint problem, a paint PROCESS problem. End result being an adhesion problem. Paint to underlying material. Likely improper surface...
No impact. Yes, rear bumper. Regardless of the underlying material, blistering paint appears to be a chronic problem. Given it's a multi-surface material problem. Deductive reasoning would lead me to conclude the root cause to be a painting process problem.
