Painting defect cause?

Awesome information thank you. I sprayed the metal steering column with Eastwood Rust Encapsulator matte black, the rear seat upper metal trim with both DupliColor Caliper paint and Krylon self etching primer. Also used the caliper paint on the plastic door arm rest mounts. I think there was some sort of armor all on these as I’ve never had an issue like this and painted quite a bit. I am Planning on stripping them all and using wax/grease remover like Pre, then the self etch primer, then I may grab a different paint. I always buy lots of different brands, have yet to find a durable matte black that isn’t $25 a can like Spray Max or the Rust Encapsulator.
