Newbie poster here. I realize that frame painting has been covered in many threads, however I'm looking for specific advice from anyone who has experience painting over powdercoat.
The bike is steel frame, with a white powdercoat finish. Finish is in excellent condition - but shows dirt way too easily. So I want to spraypaint over in a darker color, probably just black. I'm open to unconventional finishes like chalkboard paint, grill paint, etc ... but only if someone has experience that they're very durable when used over powdercoat.
So, questions are - has anyone successfully spray painted over powdercoat? If so, how did you prep the powdercoat for painting? What brand of paint did you use? Technique? Number of coats? I know there are spraypaints formulated specifically for painting plastics, should I be looking at those since powdercoat is plastic?
Looking for advice from those who've had success with this.
