A new kind of MOUSE–the NMR mobile universal surface explorer –makes NMR investigations possible on composites with ferromagnetic components, which were previously excluded from such studies, because inhomogeneous magnetic fields are used in the first place. An example application is described, to relaxation measurements of polyvinylchloride (PVC) coatings on iron sheets. It is demonstrated that new and artificially weathered PVC coatings can be distinguished by means of their different transverse relaxation times.
