Absolutely Amazing!
If you are seeking a high-end sealant resembling a “High-End Wax†appearance and a real show car result, then look no further! Klasse High Gloss Sealant Glaze is your answer! Just stand back and be prepared to see and feel real professional results. Supper easy on and off. I applied by hand with Autogeek’s microfiber applicator pad and was just as easy to apply as well as remove after cured. The end results are an exceptionally slick, high gloss finish and appearance. I kid you not, Klasse High Gloss Sealant Glaze is THE BEST. You will not be disappointed.
ProsThis is without a doubt a 5 Star Product!!!

very easy to use
tried this on my wifes 2016 mazda mx5. it was 6 months old, through a penna. winter, clay bared first, then used Klasse sealant. followed the directions not to use too much. very easy to wipe on and wipe off. still looked good after 5 months. one weekend I was detailing and I decided to use a guick detailing wax, boy did that bring the shine back up. My wife even got comments while at work from her car sitting in the parking lot.

cloudiness on dark finishes
Have been detailing for over 40 yrs, owned a body shop for 10 yrs. restoring muscle cars and flipping cars. Haven't used an acrylic product for years (have used the old liquid glass in past) Saw the Klasse and remembered the old acrylic coatings and thought i would try it on my own truck a 2 yr old garage queen. First time I used Klasse started with AIO on an orbital then the glaze I made the mistake many did starting out on the first panel putting on to much. Yes I read the instructions, I experimented to using less and less as I went along. It did become easier to remove when I WOWO, but it seems like your removing to much product and not enough is left n the surface. Some say let it dry for 24 hrs. I experimented with drying times 1-4 hrs using the finger drag test to see if it had dried throughly and its was a bear to take off regardless. (kind of like the blue coral treatment of the 60-70's). Used detailing spray to help removal. Would hate to try and remove it after 24hrs. Bottom line this was a black truck that has been yearly clayed, polished, and waxed 3-4 times a year (Griots products and orbital). After using the Klasses there was a definite cloudiness, dullness it did diminish over time but not completely. I think its a by-product of acrylic as acrylic isn't truly a clear finish when reflecting the light. (go to a glass store or H.D. and compare a piece of glass to an acrylic piece .)To some they wouldn't notice it unless they saw a good canuaba wax on the paint. But people like ourselves would. I can see this not being as noticeable on a lighter color, but its there. No I'm not talking lack of depth, that was expected. I may sound like I'm knocking Klasses its just that time has passed it by.
Pros in its time its was the best for durability and lasting
ConsTo much time and effort. There are better and easier products to use out there especially the new ceramic coatings. Recently re-did the truck in pinnacle diamond coating, yes more expensive but, now the paint pops, clear, mirror finish and no cloudiness like the Klasse. Still no depth but thats what the top coat of canuaba's for.

Amazing Sealer
I have used Klasse for over 20-years and have been amazed at the quality of finish my cars have. I alternate using Pinnacle Souveran Carnauba Paste Wax with the Klasse, which improves the depth of shine. I have not had any problems removing the Klasse, which some people mention. I suspect that they were no diligent in waxing their car.

ProsI so happy this shine is to last 8 months. I know I won't wait that long but it's good to know when you can't get out due to weather and put on a second coat. GET IT GOOD STUFF!

Appears to protect well but is hard to see
I put it on a truck that sits outside year round. I'm new to the product
ProsThe rain still beads on the hood a year later.
ConsI found it to be hard to see. When you put it on sparingly it's hard to see any haze so you know if you have complete coverage.

Great product
I've used Klasse sealant for several years. I alternate Klasse with P21S paste wax based on Autogeek recommendations and have been extremely pleased with the results. Further, I like the fact that Klasse is silicone-free and still produces a very high-gloss shine that lasts well. Living in snow country, I try to get two coats each of Klasse and P21S laid down between May and October. The last application is always Klasse and I still have good water beading in the Spring.
ProsHigh-gloss. Silicone-free. Easy to apply.
ConsTakes some effort to get it off; an electric polisher helps a lot.

Been doing a 3 step process for years. Start with the Klass AIO, followed by the Klasse High Gloss Sealant Glaze early in the mornings. Let the vehicle set for the glaze to cure on the vehicle until the next day. Next day for the 3rd step rinse and dry the vehicle off and use non cleaner carnauba wax which is a soft wax for a third added protection. Ordered it from Pinnacle Wax that sent all three and been very happy with the results ever since.
ProsSuper happy and easy to use following the instructions.

Excellent Results
I purchased a 2000 Chevy pick up from my neighbor for a song. The black paint finish had been badly neglected resulting in severe oxidation, rain drops that had etched into the paint, and strange little "scratch" marks all over the hood, perhaps from sand that blew up from coatings for icy roads. I had to resort to rubbing compounds, (Meguiar's 101 and 201), which helped a great deal. Then I decided to try Mother's cleaning/waxing system for black paint. It's quite a process, but it actually helped suppress the small scratch marks and give a good wax shine. That product has black pigment in it. Then I figured I better get an acrylic sealer over the paint and chose Klasse. Wow! it did make a difference -- a mirror-like finish. I'm sold on Klasse sealant. By the way, I used it on, I guess it's plastic on the front and back end, after a lot of cleaning effort, and the Klasse gave it a nice shiney appearance. To apply the Klasse, I used a circular blue microfiber applicator. I dampened the applicator slightly with Meguar's finishing touch mixed with half water in a spray bottle. Then I put a small amount of Klasse on each side of the applicator and folded the applicator in several directions. I made long swipes on an area of paint leaving a space in between the swipes. Then I went back and moved the Klasse evenly over the particular area, e.g., half the hood. I let it dry then wiped it off. Mostly, it came off pretty well, but if I had problems, I just sprayed some of the half mix of Meguiar's finishing touch to remove the Klasse residue. That seemed to work well for me. Like all the directions say, use only a small amount at a time.

Easy and awesome!
Finally used this product on my new car and the result is breath taking. I have been using polymer based products for years but wanted to try this Acrylic sealant. I will never look back. Not sure why some people have a difficulty with buffing this product off. It was was easy as any polymer based products. As said repeatedly, do not apply a lot. You should barely see a light haze on the surface. I used the Sonus glaze spray on an application pad first and spreading the KSG thinly was dead easy. Another key for easy buffing is to let it dry. I let it sit for 30min but it was still a bit wet as it was humid here. After 60min, I ran a finger on the surface and confirmed it has dried. It came right off with light buffing with micro fiber towels. There are some very light streaks left on gloss black plastic trims so I used the Sonus glaze spray and the problem was solved. This product did not stain the edges of the black plastic trims at all although the plastic trims have some shallow texture on them. I did not use this product on the trims this time but I believe I can use the KGS on it effectively and if that is the case, I would use the Klasse cleaner and protectant on the interior surface and rubber parts. Very very impressed. Very versatile. Along with the AIO, I am sold. My Mini is Electric Blue and after using the Sonus glaze spray on it as a final touch, the car looks like a candy 'blue' apple!! I cannot wait to add more layers to my car.

Best in the West
Went to a car wash and the drive back, dried the car. Used the Porter buffer to put on a coat of polish, then 3 coats of sealant. I waited 8-12 hours between coats. Kept car in garage. Outside in the sun, you could see some swirls where the sealant remained. returned to car wash, swirls gone. The shine was fantastic. My 2012 is a clearcoat metallic silver and I could "read the newspaper off the shine". About 2 weeks later, "someone" spilled some glue or something that dried rough on the hood. Damp microcloth wiped off residue effortlessly. Amazing! Question- how can you put wax over the sealant, if it doesn't stick?
ProsGreat shine and durability. Polish works nicely on clean windows, too.

Part #2 of a 1-2 Punch!
After I apply Klasse All-in-One, I next apply Klasse Glaze. This 1-2 Punch is a simple process for me. What ever I apply Klasse Klasse All-in-One to, I then follow up with Klasse Glaze. The instructions say that you can apply the Glaze in multiple coats without noticing any yellowing. Well, I do and I have never seen any yellowing. I have even applied the Glaze to plastic headlight covers that I restored on my Wife's Solara and they are crystal clear. Adding extra coats of the Glaze (according to Klasse) actually increases the protection from UV and normal wear and will also improve the shine. Klasse, does however state that before applying another coat, wait at least 12 to 24 hours if possible and they seem to prefer waiting 24 hours for proper curing. The one area that you are going to have to be careful with, is the amount of Glaze that you put on your pad and the size of the area you apply it to. I apply a very, very thin coat of glaze to an area about half the size of my hood with straight back and forth overlapping strokes, let dry for about 30 to 40 minutes then remove. If and area refuses to buff clean, I mist a very light dusting of Detail spray on a plush cloth and wipe that area very lightly, one or two very light swipes is usually all it needs, they I buff by hand to a beautiful shine. The biggest question that everyone has is BUT how much do you use. I guess this question arises because of all the reports and reviews that state that Klasse is very hard to remove. I have never had a problem removing the Glaze. I usually put on two coats 24 hours apart. For the initial coat, I seem to use about 1 1/2oz. to 2oz. to do a car or SUV and for the second coat I seem to use less than 1 1/2oz.. I don't plan on using this much, its just how it seems to work out. I think that I tend to use less on the second coat because the surface is super slick from the first coat and the Glaze spreads on much easier. Remember, this is what works for me and may not work for you. You will have to experiment on you own car to find that happy medium. One last thing, I can honestly say that I get at least 6 months protection from the 1-2 Punch of Klasse. I can't say that I get more because I Clay, Klasse AIO and Klasse Glaze every 6 months, once in the Spring and once in the Fall.
ProsI think that I said it all in my review.

Does not hold contaminants like carnuba
I live in the desert in California and work beside a railroad track. I purchased a new truck and immediately waxed it with mirror glaze 26. It looked great, but when i washed it 3 days later it felt like it was holding in so much dirt it did not feel really smooth. I think the carnuba melts in the sun and just holds all the dust, sand and railroad dust. I have since started using Klasse and i do believe that while it does not Look as deep, it does not feel tacky or feel like it is holding onto dirt. It washes clean and feels smooth. When i have parked next to sprinklers, the dried water spots come off very easily. Note* Use a good orbiting buffer to apply and LOTS of detail spray and very little product. My truck is Arctic White and 2 years old and the paint and chrome still look brand new. Hit a spray wash every Tuesday and take 10 minutes to wipe dry, hand wash every Saturday. Claybar, polish ( optimum 2 and optimum finish ) then end with 2 coats of Klasse every 6 months. I am no great shakes at detailing, I just watched the videos and went out and did it. Clay bar takes a whole day, the next day polish and 1 coat of klasse and the next day a second coat. Use Meg 40 on the outside trim and Aerospace 303 matte finish on the interior. Good use of 3 day weekends.
ProsGreat shine, seems to repel most contaminants, easy on easy off. Lasts quit a while.
ConsAs other have pointed out it can be a bear to remove if not done quickly. I have found using a DA with lots of detail spay works best and then wash and dry after.

Great stuff. Although thought container was larger. 17 oz. ain't much!
Klasse is a great product although initialy I thought I would be getting more product. I will say though you don't need much when applying to get a great shine. Also they make the opening small so you don't accidentaly poor to much, which works great.

I think I like it
Decided to wax my 4 day old Mazda with it. I applied it to the entire roof with my Porter cable and had a hell of a time removing it. I soon found that you need to put it on a small area and immediately buff it off. If you follow the instructions and let it dry to a haze, you are toast! The good news is that it take an incredibly small ammount to do a car, I doesn't leave all that white dust when you buff it off, and it doesn't turn white if you get some on that black plastic trim. It's actually quite ecconomical as a pint will do countless wax jobs. Cleaning the applicator pad is a snap as the is virtually no residue left on it.
ProsGoes a long way, easy to apply, no white dust, and doesn't stain black trim.
ConsHell to buff off if you use too much and let it dry too long.

Pioneering product
Carnauba wax provides the best shine, but its durability is questionable. Car makers have tried to address this for many years; one of the earliest products to do so is the Klasse line, now about thirty years old. The all-in-one (red bottle) is a polishing wax: over the years it has gotten milder and milder abrasives, but otherwise stayed the same. The sealant (silver bottle) was always pure acrylic sealant, and its trump card was that nothing, not a thing, came close for durability. But time is catching up with Klasse. It is still the most durable; and if claims that you can go a year between applications are a little optimistic, it will certainly last six months, easily. But the polymer sealants are catching up: they have better shine (close to carnauba), better slickness (a weak point for Klasse), and their durability is nearly as good--although not quite. They are also, in general, easier to apply, or at least more difficult to apply badly. But the polymers haven't yet eclipsed Klasse, which is why it belongs in your garage. I use Klasse all-in-one (red bottle) once a year in the fall; I use sealant (silver bottle) more often, every three or four months. I have used Finish Care high temperature wax as a topper in the summer. The polymer sealants may yet catch up; right now, Klasse still has the edge for people who don't want to wax their cars once every month or two.
ProsGood shine Very economical Excellent durability
ConsEasy to misapply: use sparingly Lacks the depth of gloss of natural waxes (as is the case with all synthetic products)

Works as advertised.
I didn't want to pay an exorbitant charge when offered sealant on my new 2014 CR-V. I bought this product and applied it myself for just the cost of the product and a little time. It's easy to apply and wipe off and buffs up nicely. My car is garaged and that helps protect the paint as well. I've also applied it to a 3 year old Accord and it looks great. I would drink this stuff if I needed a protective coat for my innards.

The Best of the Best
Living up north in tough winter weather there's no better product than Klasse to protect your paint. I've tried them all and this stuff lasts the longest. I use the All in One followed by several coats of Klasse right after winter and a few coats right before winter and my car looks fantastic and protected all year long.
ProsLongest lasting product I have found with an exceptional shine.
