I've had the KB CF rear wiper delete cover in for a few months now and noticed a ring of rust on top of the hatch today. Has anyone else had this issue. The other issue I had was when I originally installed the thing I couldn't get it tight enough to not allow the cover to move in the wiper hole. I ended up using two of the rubber gaskets to allow enough compression to seal the hole and not allow the cover to rotate or move in the hole.

Which wiper delete covers are you guys using?

 

Home Depot stainless steel powder coated, I forget the diameter. Been years never had any rust issues.
