Default I Knew Better...

...but I Wasn't Thinking

I think I know what happened here, but can anyone tell me and help confirm or deny my suspicion?

You didn't acetone or scotchbrite before using a self-etching primer?

I used both acetone and an Alumiprep etch prior to the selt etching primer, same basic process I have used on all my prior primed parts.

The first 12 ribs were done with a half can but the last 3 were a new one; same issue.

I've had that cracking/flaking happen when I applied way too much paint (or primer) to the surface.

My guess is moisture. Compressor filter failed/bypassed or moving from air conditioning (cold part) to warm humid outside?
