I recently re-dipped my wheels (2 weeks ago) after initially dipping them in the beginning of April when I got the Jeep. The reason why I re-dipped them was because as I was washing the Jeep and hosing off the rear driver's side wheel, I noticed that the dip on the center cap wasn't adhered anymore. I re-dipped everything and they all came out better because I was more experienced. However, the other day I noticed that there was rust marks on the same wheel, coming from the center cap. I washed the whole thing and noticed the same marks. I'm wondering what could be rusting and if there is a problem with the center cap or something. Any thoughts?
