Clear Coat Yellowing

Any thoughts on causes of newly applied clear coat over freshly painted white to start yellowing? Started to yellow after about a week.

Self condensing of the isocyante due to water contamination, that would be my guess. Urethanes cannot tolerate water unless they are specifically designed to be water reducable.

yellowing of whites that have been clearcoated

I have found that you must use non-staining body fillers and use an epoxy sealer/primer to prevent this.

Is the clear yellowing in spots or rings? or entire panels?
