Mine are starting to look like **** with little small rust spots. Not impressed at all. Any of the aftermarket ones on CARiD etc look ok?

 

Would you mind providing some pictures? Are you sure that these "rust spots" are not oxidization on the surface of the paint? I had this issue on my previous car, and it was just a bad quality item on many GM vehicles that came with painted B-pillars. It's something a good polish like Meguiar's couldn't fix, but it required a DA and I did not, and still don't, have one. Secondly, if it is actually rust, doesn't Nissan have a corrosion warranty?
