is it possible that you still have that fine dust created by the sanding process? that would give something else for the paint to stick to.I spray painted my truck after sanding it with 400grit paper and the paint wont stick to the doors whats wrong?
You didnt prep/clean body good enough. Alot of people thinks sanding is good enough to remove grease, oils, wax, etc but it's not. The doors are the most handled part of a car, plus alot of people uses armor all on interior, and weather stripping.. That stuff is like a greasy wax.





Before painting





You need to wash car with soap and water 1st and dry it, then wipe down with prep all type grease and wax remover.. Then sand..





After you sand you need to blow sanding dust off, and wash again, and wipe down with prep all again





Then paint..





Also best to wear some type of rubber-ish gloves when doing body and paint work and your skin has oils and salt in/on them. You can cause paint to fish eye or not stick just by touching the metal with your fingers.
Seems like you have oil or wax on the door, wipe it off with laquer thinners and use a ';tack '; rag just before you repaint the door. This should help you out --- good luck !
its got wax or dirt or something else on it
