Great stuff
I've been using Klasse High Gloss Sealant for years. My car just turned 15 and looks better than the day I picked it up new at the dealer. I use the sealant once or twice per year.
ProsProtects great.
ConsA little hard to remove...but worth it.

Excellent product but when they say a thin layer, they do mean a thin layer; that’s all you need !!! Use a sponge applicator...

Autogeek, Klasse and a Vette
Several years ago I decided to get serious about maintaining my 2000 Magnetic Red Corvette. I got lots of great tips from Autogeek regarding interior and exterior care. Of the products recommended I chose Klasse All-In-One polish and Klasse High Gloss Sealant Glaze. I couldn't be happier with the results I achieved using these two products. We are now using Klasse on all of our vehicles. A little elbow grease and a little Klasse keeps our cars looking like new.

A bit tricky to use, but shine is fantastic
This stuff has delivers great results, gives a highly reflective shine and improves the overall clarity of paint, especially metallic paints. I used this product several times already, following both manufacturers instructions and techniques used by other detailers from different forums, with the purpose of making removal a lot easier. But I accidentally "disobeyed" the manufacturer's instructions on not applying in direct sunlight, but take note, it was not applied in direct sun on a very hot surface. I applied it in sunlight (7-9 in the morning), with the paint just warm to the touch. So on it went, with very thin coat, I allowed it to dry around 15 minutes in the not so extreme sun, removal was much easier than I ever experienced. I usually remove it with one damp microfiber to remove the hazed product and another dry, fluffier microfiber. It does have a slick feel after removal, that gets better after the sealant has cured for 12 hours. Water beading is good, but seems to be more of a sheeting product. This could be a turn off for some, but water sheeting does have its advantages, in my opinion.
ProsThat mirror-like shine Durability A bottle lasts a long time, a little goes a long way With proper technique, it is surprisingly easy to use
ConsCan still be a bit tricky to use Water beading/sheeting properties

So far so good
Just applied this the other day. Appears to have done a beautiful job of protecting the finish. You can physically feel a difference in the paint. It is really smooth and the shine is excellent. Time will tell to see how well it holds up

Seal before you wax
Directions say use 2 ounces per car. If you don't put it on thin it's hard to wipe clear. Hard finish for such a thin layer. Great start to a shiny finish.
ProsHard, shiny finish

I put this product on a new white Lexus and a new black 4 Runner. Even though the cars are new, I still clay barred the vehicles. Since I live in Miami and it is really hot here, I worked on it late in the evening and early in the morning to avoid the heat. I used two photo lights so I could get a really clear view of what I was doing. The product when on as advertised. Pursuant to the on-line advice, I gave my applicator a quick periodic shot of spray detailed and made sure to work the product into my applicator. It went in very easily and left a noticeable film behind. I coated the entire vehicle and then started the removal process. It wiped off very easily and left a deep shine behind. The next day I washed the cars again and gave them used a blower to dry the cars. I applied another coat to both cars and completed the process. That evening, I applied Pinnacle wax to both vehicles. The shine is nothing short of amazing. The 4 Runner's metallic black has a shine deep enough to shave by. The white metallic on the Lexus is incredibly beautiful. I always use the Pennacle products on my cars. The car was shampoo is great and using the quick spray wax afterward will leave a beautiful and deep shine. In other words this is some really good stuff!

Nice finish
I have not tried it on all my cars yet but did apply it to dull paint on my 49 Studebaker. I started with a meguiars #7 glaze to bring out the color and nice squeaky finish. I applied several coats of Klasse SG for a little extra shine and for the protection. I have not taken it out or washed to see how it beads. I will let it cure at least 24 hours first.
ProsEasy on and off and very little product is required so it will go a long way and should do the rest of my cars
ConsIt had some streaking when some water got on it and I wiped it off. Put a little more on and it went away.

Worked well for me
I'd read reviews about how great a sealant this is but how hard it can be to remove if you did not apply it in a 'whisper thin' coat so i was careful when using it for the first time. i used it on my 14' white enclosed utility trailer. I had been using collinite 845 with excellent results in the past. i started by stripping all old wax off with a wash designed to do so then dried. i used a small cloth applicator and did my best to apply a VERY thin coating over the entire trailer, i use a horizontal wipe over the entire panels then a vertical wipe over the entire panels. i was surprised how far the sealant went before needing to add more to the applicator, you develop a 'feel' for when it needs another drop added, it's quiet difficult to see the product on white paint with the very thin coat required. it only took about 1/2 an oz to do the entire trailer. i allowed it to sit for an additional 45 min after i had finish applying (that took about an hour) before buffing to remove. as previously mentioned i was worried it may be difficult to remove but it wiped off with a microfiber towel without any problems what so ever. i must say i was impressed with the end results after only one application. i've read maximum shine and durability come from a 3 coat application but i haven't had time to add any additional coats at this time so i'll have to comment more on that next time. it's mid to upper 90 degree temps now so it seams like a brutal summer is on its way so i'll see how durable this sealant is.
ProsEasy On and Easy Off, I had no issues at all buffing off with just a clean microfiber towel when applied in a 'whisper thin' coat as instructed.

Klasse High Gloss Sealant Glaze 33 oz.
I purchased this product a couple of years ago and found it to be the best sealant around. It is a little expensive but it is worth the extra price.Just clean a portion of the car,fender,door,etc at a time with a light polishing compound first and then apply the Klasse. A little goes a long way, let dry and wipe the light haze and be amazed. I find that the shine lasts for several months.not like waxes or polishes that last a week if your lucky. GREAT PRODUCT !!!

Klasse high gloss sealant glaze
Really like the end results and durability. Have used this product for years and still haven't found a good way the remove the product from the paint. Have tried to remove the product after 10 minutes of drying to 5 hours of drying time and no matter how long it's dried it's hard too remove. Have tried many different suggestions with a little water or a detailer to help with removal with little success.
ProsGreat protection and durability.
ConsHard to remove.

It's great, but............
I adore Klasse "A-I-O" (red) beyond words. Cannot say enough about A-I-O as a cleaner and surface prepper which also leaves a layer of protection.......... If only every product was half as great......... Klasse "silver", the high gloss sealant is exceptional to say the least. An outstanding product through and through but once applied (which could not be easier) and allowed to appropriately dry and therefore ready to be buffed off....., nearly impossible to buff off. I hope this review finds its way back to Klasse in Germany and they take if possible steps to alleviate such insanely difficult final buffing.
ProsA net result excellent product that does not candy coat the vehicle as most sealants do.
ConsRefer to my above review.

Time-tested product
I have used Klasse's Sealant Glaze since 1984. Back then it was a different formulation, but set it's reputation as a superior product. I have used the current formulation for as long as it has been available.... same superior shine, ease of use, and protection. I recommend it HIGHLY!!
Pros"Wet" looking shine Easy application Lasts a long time You don't need to use much.. goes a long way.

Great product - last a long time
Works as advertised...goes on easily (APPLY IT THINLY). Not as difficult to remove as some have suggested. I simply added about 3 parts sealant and 1 part quick detailer into a small mister - shake very well. 2oz total will do 3 coats on my BMW 3 Series.
ProsEasy on, last a long time
ConsCan be finicky if you don't follow instructions and apply SPARINGLY

This is truly a great product. I have been in the Automotive Refinishing all my life. We just did not have sealers like this years ago. I put on two coats on my S 55 and my wife's E 550 I really did not except to see much difference, if any. I keep both cars in emasculate shape anyway. I could tell after the first coat, that there was a higher gloss than before. I used the Klasse, on the Piano roof, chrome and even the wood grained interior trim. I'm very pleased with the results, and I think this is a different five star rated product.
ProsResults, cost, easy to use.

Seems to work well
As everyone says, you must put it on in small sections and remove quickly. Then do a second coat, which then comes off much easier. Time will tell how long the coating will last, but after 3 months it still looks good. We will probably re-coat it again in a few weeks just because we tow our car behind a motorhome and it can get really grimy sometimes.
ProsNice gloss, small amount goes a long way
ConsA bit pricey, must work quickly at removing, especially the first application.

Excellent Product
I have been using Klasse Sealant for almost 1 year. It's such an easy product to apply and the results are astonishing. Prior to using Klasse I had been using a Griot's Paint Sealant which doesn't come close in shine or lasting protection in my opinion.
ProsEasy application Dries clear lasting protection
ConsNot available in a larger quantity than 330z.

Sealant Glaze
Bought 33 oz. size. Good deal when on sale. If you clay bar and keep your car clean, probably don't need the All-in-one polish. A little goes a long way. Should last several years for average guy for home use.

I have been detailing cars for over 30 years and by far this is the best cleaner wax for the shine and longevity. You must use the glaze to get 8-12 monts of protection but the shine and cleanliness of the paint with this product alone is outstanding! I have many many customers that are blown away at the results!

The glaze looks great over the All In One. The key to applying this is thin. I like using a orbital buffer better than by hand.

Great Product
This is the best gloss sealant on the market. I used it as a base coat on all my cars and motorcycle and the shine is amazing. Its easy to apply but i don't let it stay on too long because it can be difficult to remove. Several light coats work best. I use it on wheels as well and it is better than wax by far. Have even used it on my granite countertops. Works great. Highly recommend.

Great shine
I have used many, many products and I've got to say that this All-in-One and the Finishing Glaze are the easiest to use that I've experienced. Everything else was leaving surface imperfections that were bothering me --- not so with KLASSE. The finish is as near perfect as its ever been. Appears to be a great product that you can trust to make your car's finish like a mirror!

5 star product
I live in San Diego where it is warm and carnauba melts off the car within a month. This product lasts about 9 months if I layer up 6 coats of the sealer glaze and is almost as much of a wet look as carnauba. If you show your car, you can put carnauba on top right before the show and you are there. I got tired of monthly detailing so changed to Klasse about 4 years ago and my cars look great
