"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. "
Now you can SAVE MONEY by buying resin in bulk premeasured bags to refill the reusable plastic cartridges that come with the system. The resin replacement bags are easy to install and virtually hassle free. You can change the resin in less than 5 minutes. Simply unscrew the watertight housings and remove the resin cartridges. Properly dispose the used resin, rinse cartridges, and refill with new resin. Then, put the cartridges back inside the housings and reattach it to the body of the unit.
It’s EASY! You’ll receive 6 replacement bags that will deionize approximately 900 gallons of water.
