Started to spray the inside of my car and the paint took the look of dried Hammerite.

It's been rubbed down, degreased, sprayed with upol acid 8 etch primer and left a week.
That to me looks like moisture has got into the paint. Either by it being on the panel before you started or by forming in condensation while you were in the car and painting it.
I'm a paint engineer but I only paint cars at 21 degrees and 65% humidity and with 8 robots!
