@mwichary I'd just assume/guess poor adhesion due to poor or no prep work / priming. The parts that did not stick as well, wear away easier/quicker, leaving behind what did adhere. If it's something else I'd love to hear. Another idea: a reaction between different kinds of paints (oil vs latex or whatever). This kinda falls under poor/wrong prep though. I've seen reactions like that between paints, poor adhesion, etc.
