I’d be quite surprised if your Wheel Woolies have inflicted scratches on the wheels, as they don’t have any exposed sharp parts. If they’re throughly cleaned after use to remove any embedded grit they might have picked up, there shouldn’t be any hidden ‘foreign bodies’ trapped in the fluffy heads to inflict damage next time they’re used either. I’ve been using mine for over three years now and have never had any issues with them inflicting scratches. I do make sure that I use plenty of washing and rinsing water with the Wheel Woolies, and I also make sure they’re thoroughly washed out after use in a bucket of clean water to remove any grit that might be trapped in the fluffy heads before squeezing and shaking out any surplus water and then leaving them to air dry.
I’d expect a reputable wheel refurb company to give a guarantee on their work, although with diamond cut wheels, some refurb companies may not provide as long a guarantee as they give on painted/powder coated wheels. Did you have the wheel fully refurbished or a SMART repair? From your picture, the finish on the surface of very edge of the rim where it meets the tyre looks a little rough and uneven - not smooth like the factory OEM finish would be or what you’d expect to see if the lip and, if necessary, the face of the wheel had been re-cut on a diamond cutting lathe as part of the refurbishment process. A diamond cut wheel that’s had a full, good quality refurb by a reputable company should be indistinguishable from a new wheel.
Certainly worth going back to whoever you used to refurbish the wheel.
