Great project
I’ve been detailing cars for a long time and have tried countless different products, this is by far the easiest to use. It goes on easily and comes off without much effort even after letting it sit. It gives good protection and shine, you won’t be disappointed. I would suggest a good claybar first for the best results.

Won’t do without it!
I don’t like messing with cars. But we have a new car, so I was hoping that technology had caught up with my car cleaning laziness. Well it has. I just want to keep the paint in good condition and keep it looking nice. I researched a bit and chose the Meguire’s M21 sealant and the Meguire’s wash plus. After washing, I applied the sealant with a folded up microfiber cloth. I waited a minimum of 10 minutes plus. Actually, I after the new car, I did my two others, covering the entire car and truck all at once. Waited the required amount of time, then very easily wiped them down. Now all my vehicles look super shiny. The paint feels like there is a slick glass coating upon it. I live in the country on a dirt road. This sealant has dramatically reduced the amount of dust accumulation to almost nothing noticeable. Before, after washing, you could see big clumps of dust and dirt all over the car right after drying. I know there are other steps that some would recommend in between what I have done, but I’m just not that into cleaning cars. How long will the sealant last without the other steps I cannot say, but if this sealant holds beyond a month, I will be very happy. After all it was very easy to apply.

Great results
Easy to apply and buff. Beautiful shine and water beads well. Very pleased with the results.

It depends.
I chose this over Carnauba Wax for it's durability. We're in the mountains where the cedar pollen is like snow and literally coats your car like fur; no exaggeration. At 2,300' we get thirty-five to seventy inches of rain. It snows a half dozen times a year and we get a lot more UV than one's car will get on the valley floor at 150'. After proper multi-step surface prep; 1. Wash with Meguiar's Gold Class Car Wash. 2. Clean surface with Ryobi, 6" orbital sander and 6" terrycloth pad combined with Medium-Cut Cleaner. 3, Polish surface with Ryobi, 6" orbital sander, with Hook-Loop Velcro strips attached to pad and polish with Ultra Finishing Polish applied using a 6.5" soft foam polishing pad; the yellow 6.5" foam pad. 4. Finish using the yellow 6.5" soft foam polishing pad, the sealant goes on very easy and with a micro cloth, comes off equally easy and leaves a very satisfying shine. (this product has a high splatter factor so make sure to smear around on surface before turning dual action (DA) buffer on) Why the removal of a star, it's not a wax but a sealant and one become addicted to a wax shine vs the shine provided by a synthetic sealant. Yes, it's a compromise between wax and sealant and in the harsher mountain environment, I begrudgingly choose the sealant over wax. In the mountains, we wash as regularly as possible (every week or two) and re-seal the Durango, three times a year. The car was last sealed this year in April and we expect/plan to re-apply sealer again this Summer in August and then again in November in preparation for Winter. Being new to this product, as I get more experience with this product, I'll come back and amend my above comments to reflect real world experience.

Fantastic Finish Favorite
If you like your wax / sealant for your car to really reward you for your effort, this is great stuff. I have used NXT 2.0, Meguiars Gold and Right Stuff Professional for many years. None of them. Not one of them makes my car shine or glow like this product does. Nothing sticks to it. Bird poo, bug poo, bug splatter and everything else seems to have no ability to stick to the paint. When you wash, dry or otherwise rub the finish it feels so slick. Water beads better than I expected. Compared to the products I have used the only one that is close is NXT 2.0. That product is about half as impressive as this. Carnauba Gold is great for the first 2-4 weeks and then caput. Right Look is just okay because it lasts for about 4 months. Product Pros: 1- Easy application To CLEAN surface. 2- A little goes a long way. 3- Smells kind of okay. 4- Works great on hard plastic. 5- No dust when removed. Cons: 1- Bonds to paint thus slightly harder to remove. 2- Must fully dry 15 minutes or more. Conclusion: Buy it before they change the it... This is the greatest I have used yet. Enjoy!

You Wouldn’t Guess She’s 16!
ORIGINAL: “Sandy” is a 16 year old Solara who has spent a good portion of her life basking in the harsh Florida sun. I try to wash her every 2-4 weeks and wax every 2-3months (she’s high maintenance when it comes to her appearance.) I am a regular user of Meguiar's products and have used Gold Class Wax and Ultimate Wax before. While the other products aren’t bad, I prefer M21 for it’s easy of hand application and removal. When applied in an appropriately thin layer - it buffs off without any effort. I use these applicator pads: https://www.amazon.com/Adams-Yellow-Waxing-Grip-Applicator/dp/B005DNBE72 and quality microfiber towels for buffing. Sandy might be an older gal - but with M21 she can still turn heads. UPDATE: While I still like the way M21 makes Sandy glow, I am unhappy that my half full bottle has separated. The product is stored inside so temperature is not an issue. No matter how vigorously I shake the bottle of M21, the product will not become homogeneous. Instead, it appears as purple liquid suspended within a clear oil. Will probably switch back to Meguiar's Ultimate Wax for my next purchase.

Better than I expected and I expected a lot
Read the great reviews and expected a lot. This exceeded those expectations. We bought a new (used) car and after getting it for a while I noticed that it was picking up scratches REALLY easy. I don't know if the previous owner never waxed it or if the dealer buffed the heck out of it and wore off protection. Anyway, it was getting little scratches everyplace. I tried the special scratch removal polish you can buy and it was moderately effective. Then I tried this. The scratches/swirls are gone. And I think the finish will be more durable (but I can't verify yet as I just applied it last night). I applied with a random orbital buffer and let it dry really good. Don't remove too soon. Then I took a microfiber towel and wiped off the majority of the residue by hand. Then buffed with a terry cloth bonnet to get the rest off. Then with a synthetic wool bonnet. There was an immediate improvement. Finish is now very glossy and very smooth. Unlike when I wax, there was a noticeable difference in places where I couldn't reach with the buffer and I had to go back by hand. In comparison, those places were flat and dull and the color was not as rich. The best thing is, a little of this goes a long way so I have lots left. This will go onto all of my cars and I'll use it regularly in the future.

Ultimate...
When I put on my dark red car there were a few scratches. The polymer bonding creates a "fill-in" effect which makes minor scratches disappear. Yup. No kidding.

Nice smooth finish
Easy to apply and buff off. Nice smooth finish on the car after the application. Still monitoring how long it last before the next application

Great lasting shine.
Very easy to use if you follow the instructions. Gives a great shine which lasts for 2 months or so. Also makes things like bird dirt much easier to remove. OK for shiny plastics, but avoid any textured surfaces. Also good on door shuts, will help to stop the weather seals sticking in freezing weather.

Ganz hervorragend dieses Produkt. Bin sehr zufrieden damit. Kann es weiterempfehlen. Lässt sich gut verarbeiten. Danke und Toppsache. Super, Klasse

Brilliant results
Holy Crap - this stuff is genius. Yes, the price tag is a bit off-putting but this synthetic sealant yields results like nothing I have ever used before. Try it on your kitchen appliances (stove, dishwasher) and it finishes like glass.

gewohnt gut
Wie beschrieben, leicht aufzutragen und einfach abzuwischen. Optisch und haptisch kaum ein Unterschied zu Ultimate Wax (soll aber länger halten).
