I have been using WG Spritz on my wheels (I know, I know). I gave the stinky bottle to my brother because I never had anything but olfactory problems with it. The new stuff is okay--I still don't have streaking problems with it. Problem is, I didn't find the dirt encapsulation powers of WG to rival either FD or FI. I still use FI, then FD for maintenance or just FI before adding a new layer.
