I only used Deinonized water on my customers cars. They also tend to marr the paint less due to the lack on minerals in the water.

You might want to bone up on the subject and make sure your not getting sold a bill of goods when using one of those DI filters. Typically ultra pure water is first vapor distilled, then de-ionized using a much more complicated process. It pretty darn hard to remove all the desolved solids from water. It's damn near impossible to do it with a screw on spigot filter. I'd agree with filtering if you've got really bad water but in most cases you're better served spending your money some where else.

I am looking to upgrade to a CR system that has an on board TDS meter and will always keep the TDS rating at 0.
And YES, the right system WILL make a difference whether or not your water is "really hard"

Hey, it's your money or business...spend it the way you want.
There are several things that should be considered when using DI water. In this case I'd be more concerned about PH than water spots. DI water has the tendency to go acidic. Needless to say there may be good reason not to use DI water due to that or the fact that it tries to re-absorb, for a lack of a better way of saying it, the ionic components that have been removed. I'm not sure if those facts have a negative impact on your cars finish or parts that get wet however in the lab it not recommended to use DI water for cleaning of parts due to that fact.
Just some food for thought...

Remember that acidity is not as extreme as you would think. Household vinegar has a pH of 3.
I would prefer a drop of even 1 pH for the lack of micro minerals marring/hazing the paint or leaving the dreaded water spots.
But again, everyone has their own way

Ive been using a 3.6 ft^3 DI tank to wash my car for about 4 months now .... I use it to rinse the car and If I am not going to apply any new coats of product I just walk away....
the water from my faucet has a TDS of around 480ppm and in this AZ heat you cant dry the car fast enough to stop "ALL" waterspotting....
After running the water through the DI tank the water is around 4ppm ... total cost is $70 for them to drop off the tank and then a $10 monthly rental fee.....
My impression is that it is the single best item for washing your car... the less time you spend rubbing your paint with a towel the lower the chance that you have to rub swirls into your paint......
