nothing but the best
September 20, 2014
easy on.......easy off if you dont use too much. I find misting with a solution of water and klasse aids in removing the final coat. I let miine stay on for 30 minutes. I was blown away. It even fiulls in minor swirl marks. water beads nicely. I can tsay enough about this stuff....and they are right. A little goes a looooong way.
durable, easy on. excellent shine. long lasting.
hard to remove if you use too much, but a spritz solution fixes that.

Klasse sealant
July 29, 2014
Did the Clay bar process on a brand new car, amazing how much junk was on the paint. Then I put the Klasse Gloss Sealant on the car, two coats. The paint just came to life, great product. The results were worth the time and effort.
Goes on very easy. Little goes a long way.
If you put it on to heavy it's a chore to remove.

Pioneering product
July 17, 2014
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.
Good shine Very economical Excellent durability
Easy to misapply: use sparingly Lacks the depth of gloss of natural waxes (as is the case with all synthetic products)

Works as advertised.
June 18, 2014
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.

AT first I wasn't sure and it said you could put tow or three coats I did the second and saw a little better shine and then after a week it really started to shine good product
it seems that after a week or so it looks better than when first applyed
still doesn't have that real wet shine look

This sealant lasts better than any I've tried and the gloss is great. However it needs a coat of wax to leave the surface slick as it should be.
Durable and glossy
Not as slick as it could be and leaves streaks unless you come behind it with a spray wax

Put AIO klasse on my wife's 2014 4runner top with Klasse glaze sealant. Left on for 12 hours and wiped off. What a shine. Its is easier to wipe of After 12 hours.
Awesome shine. Does repel a lot. Dirt pollen road grime.

The Best of the Best
April 27, 2014
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.
Longest lasting product I have found with an exceptional shine.

Goes on as advertised: thinly, dries relatively quickly and leaves very little residue. Looks great so far but it's only been two weeks-- we'll see.
Ease of application/ buffing.

Love this stuff, a friend let me borrow it. I started by clay baring the entire car, then a coat of Klasse all in one, followed by Klasse high gloss sealant. topped it off with Pinnacle Souvergn..WOW the royal blue paint on my Acura POPPED!

Amazing protection, but too finicky
August 24, 2013
The finish of this glaze is amazing, and it's staying power is in a class all it's own. But there are too many high quality sealants that are easy to use and that's why I am giving three stars. Even after taking great lengths to apply thin, I still encountered areas that were extremely difficult to remove the sealant. It has a learning curve for sure, but why out up with it when you have so many other options. Top your Klasse AIO with something else.

Great Results/Difficult Removal
November 16, 2012
Product is pretty easy to APPLY and very little of the product is used to coat an entire vehicle. Recently detailed a Dodge Challenger and used less than 2 oz for multiple coats. Major problem is how hard it is to remove. You have to literally scrub at times to get it all off, overall, great product though.

None Better
November 11, 2012
I've been waxing cars for 40 years and this stuff rocks. No, it's not a wax but is the base that will rock your wax. A couple of coats and then use of a quick spray detailer every couple of weeks will bead water like not other and your paint will be so slick that your detailing towel will slide off your hood on its own momentum. Buy it, you won't be disappointed.

Easiest to Apply
September 30, 2012
Use very little. It goes on andcomes off very easy. The easiest of any product I tried. The shine on white is amazing. I just took the car through the car wash tody and the water "runs" off. It doesn't even bead. now that is slick.

Awesome Product
April 25, 2012
Love this product. Smells great, lasts a long time, and the shine is incredible. it can be difficult to buff the residue off, seems like I get the residue no matter how little I use, but the extra elbow grease is deffinently worth the end result! I purchased the 16 oz bottle first and had to go with the 33 oz bottle recently.

Exceptional product line
April 24, 2012
Both Klasse products - "All-In-One" and "High Gloss Sealant" are, objectively speaking, simply exceptional. They truly are. For what they are designed to do; no more, no less, they fully excel and have exceeded my expectations. Their application is wonderfully easy as is their removal and the net results are as described. Simply wonderful. While I principally use both products on our cars, I have also employed same in other manner with equal results. May I say, what a product line !

Klasse high gloss sealant glaze
March 30, 2012
I used klasse high gloss sealant on my 2006 silver Corvette convertible. The shine was outstanding. It went on easy and came off easy using detailer when I buffed it off. I highly recommend it.

3 Stars
February 15, 2012
Highly reflevtive, very shiny, shine can be a bit sterile but i do find that on black while reflective does seem to be able to darken paint. Something unexpected, i didn't expect klasse to be good or deliver in that aspect. Slickness initially is good, but seems to lose that even within 1 month. But the shine is still there, in that respect i am a bit disappointed. I expected the slickness to last longer than that. Durability should be good with this. However, with the advent of newer polymer technology, this klasse seems to be getting a bit dated, other sealants can come close in durability but is much easier to use.

Road Tar
January 11, 2012
My wife drives a 2011 Honda Accord that I applied both the Klasse Polish and Sealant to in August 2011. After washing her car at a CarWash yesterday we noticed that she'd somehow managed to get some Road Tar on the Paint. From past experience removing Road Tar can require some above average pressure to remove. Let me say that the Road Tar came off easier than spreading warm Butter on a piece of freshly Toasted Bread. No Polish/Sealant combination that I've used before made this chore so easy!

acrylic sealant
December 13, 2011
Provides a nice bright shine, not the easiest to use, but somehow kinda got away with it being surprisingly easy to use on my car. Could be the applicator i used, i used a small shallow nap microfiber applicator and managed to apply the really thin coat needed to make this klasse easy to buff out. i topped it with collinite 476s and insulator wax, to add more glow to the paint. Adds sparkle to cars with not much bling.. quite finicky to use in my opinion.

Good product
November 17, 2011
Ive used this product a few times but never gotten near the durability they claim. I was using it on the door jambs in my own car due to the anti scratch claim... but with CQ out I coated the jambs with that instead. Overall a good product but I thought application was much more difficult than using a polymer sealant like UPP

Apply this whisper thin like opticoat and you'll hardly have to wipe anything off.

Used Twice, Love it
September 4, 2011
I have used this product twice. The first time I used too much as I was used to the usual waxes and silicone products. It took some extra time buffing it out, but it looked great. Now I use about half a teaspoon on one section, and buff it in with a microfiber towel. I make sure I don't let it sit on the paint without buffing it in or it will be hard to buff out. If I use a real thin coat, I don't even have to wait an hour, I just leave it as is and it looks fantastic. You can feel the difference between the surfaces. The surface you just put Klasse on will feel like slippery glass while the unfinished surface will provide resistance while running your fingers on it. Terrific product.

Great Product
September 4, 2011
I have a Toyota Tacoma that has a lot of black plastic trim and Klasse does not leave a white stain on the trim like other products. One other tip is you must buff this product out immediately and use a small nickel size amount on one section until you get the hang of how this product spreads and buffs out. Once you learn how it works you own't be disappointed!

The longest lasting sealant I have used
November 8, 2010
Application of this sealant must be thin. If not you will spend a lot of time buffing to remove all of the product. Also very important to not apply this product in the sun, this also makes removal very difficult. Long lasting protection, and easy removal with correct application, what else can you ask for?

like a mirror
October 27, 2010
On my 2009 Nissan 370z I first used nufinish polish, then I used Meguires showcar glaze, then Klasse High Gloss Sealant Glaze, Then I used Meguires high gloss liquid carnuba wax. It is like a mirror finish. The 10 inch buffer definitely helped as that was a lot of work.

You Won't use anything else
September 17, 2010
The first time I used this product, I was frustrated. When the instruction say "a thin coat" they are not kidding. To tell if it is thin enough, look at a light reflection on the paint. When you wipe Klasse on, you should see the trail left by the applicator. It should disappear within a few seconds. Leave to dry overnight and you will have a brilliant, protected surface. This product takes some practice, but the results are superior to any sealant I have used. Using some detailer on the applicator helps to amp up the shine. The resulting surface is smooth, reflective and well protected. I dropped a screwdriver on the paint and it didn't leave a scratch. Get this product and give it a chance (2-3 coats). You will not want to use anything else.

Klasse Sealant
June 6, 2010
I hated this stuff the first time I used it!!! I tried it again and now I would not choose any other sealant over it (as long as it lasts as long as everybody claims it does). USE A VERY THIN COAT!! I used ALOT of it the first time and it was a nightmare to take off. The second time around I could barely see where I applied it, let it sit on for a good 20 mins, and WOW, this stuff is amazing! easy on and easy off that time.

Ive used Klasse AIO and sealant for two years now. I use it on my Honda Accord and my Ford F150. I will not use anything else. My truck sits out all year (100F to -10F) and it still looks good after one year.The only addition I recommend is to top it off with DP Max Wax. A truly stunning combination! To see what Autogeek thinks of the Klasse/carnauba wax conbo see: I highly recommend Klasse.

The best
September 23, 2008
I love this stuff! I would clean the surface of the car completely. Then go over it with the Klasse all in one polish. Throw on the Klasse high gloss. Finish up with a coat of P21S on top. I found that using Klasse I could easily go three times as long before "deciding" to wax my car (as I don't think it ever got to a point where I needed it). Beautiful stuff, and it's so strong that it can SERIOUSLY protect paint. I accidently scraped my bumber after going through a full (10 hour) detail. As I bent down, nearly in tears, to inspect the damage there was NONE. We're talking metal on paint and it slid off without a scratch. My car (which is my baby) was purchased eight years ago and looks better than the day I brought her home.

An old Standard
August 30, 2008
I have been using Klasse since 1986. It is a great product that has held true over the years. I have applied it to every car I have ever owned and it has always delivered as promised. Whether I sold the car privately or traded it in, I always received positive comments, to the credit of Klasse, on the condition of the paint. For best results, apply several coats 12 hours apart, stack 3-5 coats and then top with souveran or your favorite wax. You will not be disappointed with the performance and shine..

Good protection
November 2, 2007
This is a great product for light colored paints and holds up well. I do not like the results on dark paint and think there are better products out there (Menzerna FMJ). Good to use if you want long term protection and are not finicky lack of depth.

I have tried this product after many years of expermentation w Zymol, Malms, Pro-yellow, etc, etc. I was prompted to do so by research on what to use on a new 22' f-glass boat used in salt water. I used the sealant on my boat, BMW & Infiniti FX...GREAT results! EZ to apply (surfaces were clean), very good gloss and after 6 months of pretty severe SC weather all is very much as it was when first applied. I believe the Zymol paste had a slightly better "shine factor" in the beginning but this lasts FAR better!!! A solid product and very inexpensive for the result.

I should have purchased this stuff a long time ago and saved myself tons of work polishing my cars. It goes on super easy and buffs to a perfect shine. Best of all, it lasts forever. I highly recommend this product. I use on my new Nissan Xterra for off-roading and it has held up beautifully. Very durable. My wife's Maxima is an 04 that still looks showroom new because of Klasse.

Combined with AIO Klasse High Gloss Sealant Glaze is by far one of the most protective finshishes available. Although HGSG may not hide swirl like other carnauba products, it is the ultimate in protection. A great product for toppers!

Part of the bulletproof combo Klasse AIO and SG. This sealant needs to be put on extremely light and needs to cure for 24 hours. Best method is WOWO and protection will exceed 4 months when used properly. Several Spray Gloss Enhancers can be used to bring some zing to it, or use a carnuba topper for a stunning combo.
