The Raptor Demo Team flew in aircraft that were from Langely AFB in Virginia, where the team is based. One of those jets showed comparatively extreme signs of corrosion on the upper nose area, right before the canopy. In fact, the section was in such poor shape, that it offered a bizarre and fascinating view of what some of the F-22's most prominent surface areas are made up of.

For aircraft that aren't headed into combat or high-end training scenarios, maintaining the jet's stealthy skin isn't as high of a priority. There are different standards of readiness for F-22 skins to be kept at depending on the situation, with its effectiveness slipping a certain percentage before needing time-consuming reapplication.
For instance, for a jet that could see combat or is needed for high-end testing and training that will leverage its full capabilities, degradation of less than 10 percent could trigger the need to reapplication and servicing. For a jet used for training new F-22 pilots, that percentage could be far greater.
Clearly, performing at air shows doesn't require any stealth at all. In fact, the jets wear bolt-on radar-reflecting lenses so that their radar cross-section appears large on air traffic control radars. So, it makes sense to send jets that are not fresh out of low-observables servicing for such tasks and using those that are for more challenging and pressing missions.
In addition, roughly a third of the relatively tiny F-22 fleet is not combat coded at any given time. Older models that have not been upgraded to latest block configurations are used for training and in some cases testing. Once again, these aircraft would likely have a lower priority for keeping their stealth cloak in check than their front-line counterparts.
