OK so you thought the first pics were snowy - well I tried the DP Xtreme foam today and its Nuts!!
I thought I'd humour Sentinel and do a few pics and also attempt a completely "touchless" wash:
Before - the car is dirty, but not grimey. Its had a full week at work in a dusty environment (roadworks a block away) and fallout. I park under a shade sail at work.

Next we foam it up - now this is snowing!


From here I let it dwell for 5mins to slump off as much dirt as possible safley as the foam lubricates the surface (never let the detergent dry on the paint surface) After 5mins it really starts to disperse and show a shiney underneath


Now I rinse with a Gerni but using a special car wash nozzle (60deg Fan) designed not to damage paint. This is the immediate result:

I then dry with my leaf blower (note since I did no mitting/sponging whatsoever I would not entertain chamoising or drying with a microfibre towel. There is bound to be small particals on the paint that were not removed by the foam and would scratch/swirl)

Looks pretty good, not bad for a touchless wash, but under direct light I can see some grime spots and a few particles still on the paint so mitting is still adviseable. But a good experiment all the same.
Perhaps a different wax may help the removal of all contaminants under the foam alone who knows
