I wouldn't worry about water spots on the black chrome.
We just got our 2014 last month and put the bc wheels on a week later.
I poilshed the whole Jeep....glass, paint and wheels with Zaino All in One cleaner, polish and protectant and then coated everything with their Clear Seal. After it is driven in the rain the paint and glass still looks clean with no waterspots. The wheels don't have water spots but do get a little grungy from the mist covering them while driving. Takes me about 2 minutes to clean each wheel. I use Meguiars Quik Wheel Detailer and it is safe for all wheels. They look like new again after a quik wipe down.
I kept my stock wheels and tires for winter to help keep the bc wheels newer/longer. I think your Jeep will look great with the bc wheels. When it doesn't rain for a while the wheels still look clean after a week of not touching them at all. The bc helps to hide the brake dust also.
What wheels did you get?
