CR Spotless DIW-20 High Output Wall Mounted System

I haven’t had much of a problem with water spots on my cars, but you guys know me. I’m always in favor of overkill. Seriously though, this thing is pretty sweet. I use it with my pressure washer to preserve the resin as much as possible.

The idea here is to “deionize” the water to ensure you don’t have any contaminants or minerals that can dry and leave spots or etch the paint. I still blow-dry the car, but this makes me not have to worry about any hard water spots.
