Dust particles that harm ceramic coating on PPF? I'm more afraid of trucks throwing stones.

Not sure if this is liked, but I really enjoy the Ammo NYC products and training videos on detailing. Check out their website and look at the FrothE stuff. The guy goes into great detail about the best way to clean and clearly explains his methodology and why some foam aerators are better than others. Hard to beat the detailed explanations. His stuff is very expensive though, there is absolutely a premium on his products. They work, though and his videos are pretty satisfying.

been using a stihl leaf blower and driving the car on dirty highways for years. No sign of damage from either

I agree. I have been detailing my own cars for 20 years or more and have become **** about it. Lots and LOTS of research and I try to do as much as possible (on the outside) without touching the vehicle with anything except water, soap and air unless it is really dirty. Highly recommend CR Spotless (or other quality RO/deionized wash system) and PH neutral soap. As far as foam cannon, the Amazon brand is just fine and significantly less $$.

Third, Rinse again - This knocks off the vast majority of contaminants that will scratch the car if you were just FFWD to step 4.

Fourth, Wash with a soft mitt. If you were to just do this step then the small dirt particles would swirl and mar the paint. Dirt on a bit is like rubbing sand into the car and could be literally rubbing sand and small rocks(and whatever else you picked up along the way) into the paint.

Fifth - Blow dry

Sixth, dry with proper towel and drying aid - Drying aid like a detailer, bedmaker, spray wax, etc to lubricate the dry tool and finish off the car.

Seventh - ceramic detail spray, spray way, etx. Adams ceramic and CarPro Reload are a couple favorites. Beadmaker is also amazing. Maquires spray whatever is also fine.
I like the above process. I would add:
3.5: Hit with foam cannon again for added lubricity.

4.5: Rinse again. Heavily. Could use a product like Gyeon Wetcoat after thorough rinse. This is a spray on rinse off sealant. Works very well.

"small dirt particles would swirl and mar the paint" seems tough to do through my PPF and Ceramic Pro.

Obviously our cars work in the rain, but the rain isn't full of automotive detergent.... Can I safely just spray everything down and rinse off? Does the intake need special care?

If it makes a difference, my car is a 991.2 C2 and is ceramic coated (including wheels and windows)



Thanks in advance!
you must never drive in the rain.

Blow dry with my trusty Stihl leaf blower, plenty of air.

Open the frunk, rear deck lid and doors, dry off with microfiber towel.

A note of warning, if you raise the spoiler to clean beneath it, there are two small, round rubber bumpers that cushion the spoiler when down.

They sit on metal tabs and are easily dislodged and lost. Lost one myself.

Porsche does not have them available as replacements unless you buy a bunch of unneeded parts as a package, and not cheap.

Found similar ones online I made work.
Part of the Neanderthal club too with the two bucket method and Sears electic leaf blower. Only I move into real knuckledragger territory by pretty much only using Griot's paste wax about once per year, and Meguirs spray on wax after every other wash. I expect my 911 to completely disolve into a pile of metallic dust by next month.

Mine is easily plugged in, usually already has soap, and moved a few feet out of the garage. Not a hardship.

Apparently this occurred in Austin, TX today outside a carwash. So, would a foam cannon or wash bucket method have prevented this? Not sure if driver is on this forum. Photo credits go to random internet poster u/caliguy18.

I love these kinds of threads. I’ve been washing cars for 40 years but invariably learn something new.
