Pretty much any surface you don't want to crack/fade. Great for dressing engine bay too since it advertises dust/dirt repellant. Not your body paint or suede interior I don't believe. But any painted plastic/vinyl, rubber. I use on my parent's 34ft 5th wheel as well.
The godsend for me has been this stuff. I can't say enough about this stuff, pretty much the best autocare product I've used. I waterless wash my truck to prevent water spots so I primarily use this to wipe the truck down to clean it 90% of time. Very easy to use even in direct sunlight and leaves my truck looking and feeling waxed every time I clean it.
I depend on the exact machine and also how busy it is.
I tend to go to mine at night when it's deserted. Then I can bring a bucket and wash mitt.
With mine I spray the wheels with wheel cleaner, use the Rinse setting to fill the bucket, then Rinse the car (not wheels), Snow Foam, clean the wheels with a brush, Rinse, wash with bucket and my own shampoo, them Rinse.
Then I spray some of this on as I'm towelling off the car.
If it's busier and I just want a quick wash I spray and clean the wheels while I'm waiting and the person before me is finishing up. Then drive in. Rinse car and wheels. Snow foam and clean the car using the snow-foam using a mitt. Then rinse. Then drive out, park up and was and dry using the same method.
I haven't tried that many, but I now generally use this whenever I wash my car as you can just spray on as you're drying the car rather than adding another stage.
Not nearly as long lasting as a proper wax. But does look nice for a while and I can't be arsed doing a proper wax every month.
There is a lot of ways but I figured I'd share what I do. I use this on pretty much everything plastic on the outside and everything on the inside. Spray Wax. It really is some of the best stuff I have ever tried. It doesn't leave a residue like Armor All and everything looks new every time I apply it. Then I keep a microfiber towel in my glove box and wipe the front cabin items every few days to keep them looking spotless between washes. Outside I use a Chemical Guys washing agent. Then I clay bar the front. For wax, I use turtle Wax Ice paste and Turtle was Spray ceramic after. Dry immediately after washing to avoid water spots. The previously mentioned spray wax works well outside the car as well between wax sessions. I usually wax twice a year. And for swirls, be as gentle as you can be. It may need a good polish after a few years but probably not.
Whatever you use, make sure you spray it down with a detailer spray when you’re done to keep the paint and trim looking fresh. This particular one can be used on the windows as well.
If you like the Quik Detailer then check out their Synthetic X-Press Spray Wax. Another user on here gave me a tip to try using the X-Press in place of the QD so I'm just passing it on. Turned out to be the best last-step product I've ever used, hands down. I just spray it on and wipe off with a fresh microfiber after I dry my car and it leaves a nice wet looking mirror finish that beads water like a fresh wax. Meguiars says it renews your wax/sealant every time you use it so that makes sense. The final result is more solid and glassy (a lot like a paint sealant) instead of almost sticky or gooey like the QD can get sometimes.
A little goes a long way too. I filled up a 16oz spray bottle like 4 months ago it's probably still 3/4 full. At this rate the gallon container is going to last a few years.
Meguiar's D156 is your friend, if you want to give it a little shine once it's clean. Spray a microfiber, wipe it on, then wipe it off. Works on plastic, black trim, everything.
Everyone here always recommends getting the 1 gallon Meguiar's Synthetic x-press wax on Amazon. https://www.amazon.com/dp/B005JPJMI2/?th=1
But honestly, I don't need a gallon, nor do I want to spend $31 on a gallon of spray wax for the little that I use it on my two cars.
Which of these is just like it? Or which one should I get? They are all within $1-3 of each other. The UQW is the most expensive and smallest bottle, so I'm leaning towards just getting the larger 24 oz bottle of the Quik Wax in the red bottle since it is the cheapest price per ounce.
I'm just going to use it as a drying aid mostly. A few sprays on each panel after rinsing off my car to provide a bit more lubrication and shine while I dry with a microfiber towel. Just to add a bit extra protection between sealant applications as well. So I know the use cases and limitations already.
This is the product I ordered just recently...
Meguiar's D15601 Synthetic X-Press Spray Wax
This product works awesome, especially as a drying agent.
For normal washes I use this.

Just spray a bit on when I'm drying the car anyway. So no extra cleaning stage.
You can go wild with this kind of thing really. Even here someone has suggested a three bucket method, pre-wash liquid and a snow foam (where you need a reasonably powerful jet wash) as a "basic wash".
For me a good cheap base would be something like this and a hose:
I would never use a sponge on paint so a microfibre mitt is an essential to me.
An upgrade to that for speed might be a wax you can spray on while the car is wet and you're drying it (if you don't dry the car you'll get lots of streaks and in hard water areas lots of white spots). Quick an easy:

I use this for maintenance washes now.
A nice big drying towel makes things much easier too. I just use a small microfibre cloth to wipe off any standing water then dry with one of these.
A sturdy bucket with a grit guard is a big plus too.
Then another without to do a proper 2-bucket method.
A spray bottle of APC is also really useful. Just dilute it as appropriate. I use under wheel arches and even for interior and carpet cleaning.
After that you can get into snow foaming, clay barring, compounding and polishing, mechanical polishing, paste wax and buffing, wheel wax, fallout removers, bug and tar removers, metal polish for exhaust tips etc
For me a normal wash is just hosing down the car to remove loose debris (including the wheel wells and underside (especially in winter with salt on the road), spraying the wheels with wheel cleaner, waiting a bit and then cleaning them with the wheel brush, spraying a bit of dilute APC around the wheel well, using a bucket of car shampoo and thoroughly cleaning the car, then hosing everything off again, wipe with a cloth to get water off, then going around with a wax spray and drying the bodywork off.
Oh boy... I wish I could find it in Canada. Everywhere's sold out or ridiculously overpriced.
Keep an eye on Olde Town Auto Spa. They list it but, you know... out of stock.
