Best combination
The first thing I did do prewash with Gyeon foam then Bathe for contact wash Meguiar clay bar then polish with Gyeon polish then prep clean. Then I added jascar ultra lock SIO2 infused sealant and topped with Collinite 845 polymer carnuba wax insulator. This is a one two step process and the gloss is insane great combination and it has water repellent the richness, easy to use and save a lot of money on a long term. The streak free , slickness and the shine. Thanks to obsessegarage video and Pan the organizer video. It should last at least 8 months with the south Texas heat. Love the results.

Great product
Incredible shine. Easy to use. Put on thin out. wait at least 1/2 hour to dry to a haze. Wipes off easily. Best sealant I`ve ever used. Lasts too. great beading action in the rain

12 year old black car looks new again!
This stuff is so good. Easy to apply; just wipe on, wipe off after making sure your car is clean. after applying it you can literally feel how slippery your car is. When it rains, i can watch the water bead off of it. Gone are the days of paying $1k+ for a professional ceramic coat. You can do just as well in an hour with this stuff. I own a 12 year old black Civic and people complement me on how shiny it is all the time now that I use this. Even the guy at the body shop couldn't believe how shiny it is. I previously tried Chemical Guys Black Light and it was super disappointing in comparison. Don't cheap out and get the good stuff!

Very impressed with the performance
I’ve been using a German polymer sealant, for quite a while, which worked pretty well. However, I wanted to try something a bit newer, and my AI platform suggested this. It has not disappointed. Went on really easy, came off easy. I topped it off with collonite 845. The thing that impressed me the most regarding the paint was when I had a couple of fairly large bugs slammed into the paint on the front end of the car. I expected I was gonna have to get out my bug sponge and spend quite a bit of time getting them off, but when I hit it with the regular water jet on my garden hose about 80% of it came off and then with a regular sponge, the rest came off super easy. I was genuinely astonished. After that, I put it on my wife’s Ford F150, water, beads beautifully, washes up super easy. However, the most impressive thing is what it did to the mag rims on my Mustang. When I first got the car, even going out for a relatively short drive after I got back the rims would be black with brake dust. The picture shown is after 600 miles without washing them, a couple drives in the rain. If you get it and you have mag rims, definitely throw a coat on. No need for a topper. I like the stuff I used to use, but this is even better.

Good but not sure about 6 month durability.
I purchased this product because it seems to be the best paint sealant (not wax, not ceramic coating) you can buy. I put it on a brand new Corolla freshly home from the dealership. Yes, the application is a bit difficult. If you can imagine putting vaseline in the freezer and then trying to rub it into your paint with a microfiber applicator pad, that's what it's like. It doesn't slip and glide around so you have to smear it around slowly but surely. Don't use too much! You also want to wear gloves when applying it because it has a warning on the bottle that says it could be fatal if inhaled. I didn't feel the need to use a mask/respirator when putting it on though. A ventilated garage will do just fine. By the time you get back to where you started on the car, it should have developed a haze at which point you can start buffing it off using a microfiber towel by hand. It buffs off pretty easily like wax and left a SUPER SLICK and shiny finish behind. Almost like an air hockey puck on an air hockey arcade table. Definitely better than wax. Fast forward 2 weeks and 2 washes later, the water beading already diminished by about %50 and bug marks want to stick harder to the paint than they did when it was freshly sealed. (I used a light concentration of Chemical Guys mr pink soap which is PH neutral and non-wax stripping and use RV filtered garden hose pressure water to rinse it off when I wash my car.) I would give this more of a 2 month durability. (It might last 6 months if your car is parked in the garage and only need to wash it once a month.) But outdoors in the elements, that goes down quite a bit. So, you will need a light spray wax maintenance coat every other wash if your car is exposed to the elements 24/7 if you want to maintain a slick water beading finish. This is better than a wax, but not a miracle sealant. I used about half of the 8oz bottle on a Toyota Corolla. I plan to re apply it every 6 months and do maintenance spray waxes in between. And of course a wax stripping wash before I re-apply it every 6 months and clay bar if necessary.

A bit pricey but awesome
I have been using for about a year on multiple vehicles, and when used with a good clay bar, this stuff will shine and protect better than anything else out there.

This is the best I've ever used and mirror shines and beeding
Omg this is the best I've used and it shines like crazy and goes on lovely and slick. Just use a little or your going to find it hard to buffer of. Buffering it off 30 mins later and so easy to buffer off if you don't use to much. The finish and beading is out of this world. I would recommend to use Colinite 845 on top of this which will make this look even crazier and showroom looks. Get colinite 845 on here and use it the same way as this but don't use 3 or more hours later for it to cure then put on colinite. Make sure you bathe colinite in boiling hot water so it turns into liquid before applying on car so it goes on and buffer perfectly 👍
