Water spot preventer

[midwestray]

Has anyone tried using distilled water in a foam gun for a spot free rinse? Can it be dialed up to have enough distilled water coming through to be effective? Sometimes when you are in a hurry it would be nice not to wipe down and add a spray wax, and the spotless rinse at the car washes around here are worthless in preventing spots. Thanks in advance!

No, that foam gun thing definitely won't work, for a multitude of reasons. If you want anything effective, but still affordable, then buy a leaf blower in the range of $70-100 (2000-3000 Watts) and use that to blow off most if not all water from the car's surface. The latter will be only possible if you have it ceramic coated or have some very good quality hydrophobic sealant on it, that allows the water to roll of. Anyway, getting most of the water off the surface will allow you to wipe it dry 10x faster with a towel, or make it dry enough so you can apply some water based spray wax or sealant, that still works fine if you only have a small amount water left on the surface. In the latter case you can actually wipe dry the car and apply a sealant/wax to it in a single pass.

We live in an incredibly hard water area, water from the tap looks like incredibly diluted milk. We always drink filtered water.

You foam lance would dilute it so much there would be no effect.

My best defence is :-
Powerwash car normally
Snowfoam it
Powerwash it off.
Use filtered water in the car soap bucket, so none can dry off milky.
Powerwash rinse thoroughly.
Then the trick is to final rinse of with the tap 1/3 on via my water filter, in a sort of “wave” over the panels.
Then blow dry with a dedicated leaf blower ... zero water marks.

Sounds ludicrous, but if you washed it and just left to dry it off; you would definitely have to Clay it here.
The water filter costs £99 , and lasts circa 36 washes and then you change the filter resin beads ... and that cost £40.
So its about £1.10 a wash. And imo is essential.
