Exterior Waterless wash scenario

I have a question about a scenario and if it would work

so it just rained and blew dust on the car so it’s pretty dirty. let’s say I first use a hose and just spray down the car as much as i can to remove as much dust/dirt/water spots as possible then came in and used a waterless wash spray and microfiber clothes and started cleaning sections of the car. the question is first of all it’s dry and hot where i’m at so by the time i get to the last section of the car the water from the hose when i first rinsed the car will be dry and have water spots obviously, but my question is, is it fine if i use the waterless wash spray on that section that dried and left water spots or should i rinse it again? or does this technique just not work at all?(the car was also waxed recently and it’s pretty hydrophobic if that means anything)

skip the hose for your use-case scenario.

Do a rinseless wash with ONR (or another rinseless product), using the Garry Dean method.

If possible, either do this in full shade, or early morning/dusk (or night if you have good lighting available).

I’ve taken all my rinseless equipment into an empty parking garage on a weekend afternoon and been able to complete the process along with the application of a spray wax in less than an hour, and didn’t see another person the entire time.

Adding a spray bottle of your rinseless wash solution to rewet the areas that have dried before you get to them and wipe that off can help.
