G'day,
Since it is flexible relative motion between both sides of the gap it is sealing might affect whether the paint adheres or not over time.

Perhaps it depends on the type of paint used.
I used PL polyurethane on a roof seam over ten years ago. I painted it with Krylon acrylic spray from a can. It was Antique White which was a great match to my GMC paint.
I was on the roof last week and the paint is still holding very well to the half inch wide band of polyurethane caulk.
Ken, what type of paint did you use? Strange that we would have such different results.
