Meguiars #21 Synthetic Sealant 2.0

New & Improved, technologically advanced paint care and protection.

Meguiar’s #21 Synthetic Sealant 2.0, part of the Mirror Glaze professional line, has been upgraded with the latest breakthroughs in synthetic polymer paint protection. Now your vehicle will be noticeably deeper, darker, and more reflective. Hydrophobic Polymer Technology repels water while producing an amazing gloss.

Meguiar’s #21 Synthetic Sealant 2.0 is made of highly reflective polymers that bond to the paint to create a micro-thin shell that is both incredibly shiny and durable. Unlike most paint sealants, #21 Synthetic Sealant 2.0 visually eliminates fine swirls and scratches to render a flawless finish. Your paint will appear darker, glossier, and smoother than ever before. #21 is designed to go on by hand or with the help of a machine polisher, which makes it equally suitable for use by a professional or a do-it-yourselfer.

Meguiars #21 Synthetic Sealant 2.0 goes on smoothly and easily no matter how you choose to apply it. Wiping it off requires no special effort. Like most paint sealants, #21 is designed for easy application and maximum durability. You can expect months and months of protection and a lasting shine.

The benefits of sealing the paint are numerous. Acid rain, industrial pollution, road grime, and UV rays cannot penetrate the tough barrier so your vehicle is less likely to incur water spots, fading, oxidation, and general contamination. Keeping the paint clean is as easy as a quick wash with a gentle shampoo.

When applying Meguiars #21 Synthetic Sealant 2.0 by machine, use a soft buffing pad. Meguiar’s Soft Buff Finishing Pad will work well with your dual action polisher. Buff off with a soft Cobra Microfiber Towel.

Meguiar’s #21 Synthetic Sealant 2.0 will give you the long-lasting results you expect from a quality sealant plus the incomparable shine you expect from Meguiar’s.

16 oz.

I think I found a new favorite product with m21. It goes on and removes easily and produces an excellent finish. The shine depth and clarity of the paint are astonishing and it's reasonably priced. It has not been on my car long enough to rate longevity at this time. If you own a dark colored car and the paint is in good shape use this product it will make your car reflect like a mirror and turn heads.
Price ease of use amazing results

If only
December 13, 2016
As a detailer, Ive used this product and bought it again cause it works easy and result were great. On a black car it works to cover scratches. (Not to contradict, I usually like to remove scratches first then protect). It does deepen the paint I use it on windows, chrome, guitars, mirrors etc... If only......it lasted longer. 2 months it lasted on a black car.

Great Sealant
November 10, 2016
Been using this product for more than 2 years and never have been disappointed or thought of switching to another brand of sealant. When you find a product that produces great results you stick with what works. Meguiras sealant goes on easy, removes easy, never streaks, produces an excellent shine and will protect your vehicle's paint for several months.
Goes on easy, is easy to remove, produces a great shine and provides lasting paint protection.

I purchased this because I was looking for an AIO with little to no abrasives but had a chemical cleaner and sealant protection. My car has excellent paint and needed no correction. Very fast and easy with a DA and soft pad. Car looks great.

Awesome sealant

This product goes on and comes off with little to no effort. The shine that it leaves is blinding. I love this stuff. I have 2 black vehicles and this stuff makes them shine like a new coin.
Leaves the paint slick, makes a QD even that much quicker

This stuff Rocks

After a little research I thought I would give this a try on my 2015 Tacoma. I washed and clayed the truck then sealed it with M21. Wow, easy on with a foam pad let it dry to a haze and use a micro towel to get the haze off. So happys with the results.

As far as putting it on and taking it off this product is a dream. As far as protection and how long it last I'm not sure yet. I topped this with meguiars ultimate wax and the depth and shine is awesome. Very pleased with all of the meguiars products I used

Best in Class
December 13, 2014
Using Meguiars M105 Ultra-Cut Compound, followed by Meguiars M205 Ulltra Polish and finishing with Meguiars 21 Synthetic Sealant I was able to restore the finish of a black 1995 Camry to almost a new shine and luster. I've taken exceptional care of my cars for years but this combination for products from Meguiars has proven to me to be one of the best. I've used a variety of car products especially Mother's for years, thinking they provided the best results. Meguiars proved me wrong. I seldom write reviews but these products warrant my time.

#21 sealant is easy to apply and remove. I used a random orbital polisher on one car to apply and remove, and the edges by hand. Second car was done all by hand. Product leaves a hard, smooth finish. Almost all swirl marks were concealed, and a second coat may remove them all completely. Circular rubbing of the surface with a microfiber cloth after a few days left no swirl marks. Very happy with the product. Waiting to see how long the finish will remain.
Ease of application and removal. Hard, smooth finish. Very little product used to seal car.
A little pricey at $25, but comparable to what other manufacturers are charging currently.

Amazing Results!
September 10, 2014
This paint sealant is an all around great product. It goes on simple and wipes off even simpler. It has the consistency of warm butter, not so thin that it is runny but not too thick so its simple to wipe on and off. The results were absolutely stunning and the week after I applied this sealant it rained almost every day so I got to see all the tight water beading that happens with it! It is just unbelievable watching the water fly off my hood, I get distracted while driving! Keep in mind, this is considered a finishing sealant so don't expect this product to give you outstanding results unless you prep your car properly by claying followed by at least a pre wax cleaner. Now my car looks slick as a sheet of glass and shines like a mirror! Next time I'm going to let a coat seal and then try a second!
Easy application, very affordable for a professional product, purple color helps show you if there is too much product built up in one spot (especially on my white car), and absolutely stunning results!

Great Product
June 20, 2013
This stuff is so easy to use and last for a very long time. I love that it doesn't stain black plastic and dirt and bugs get raised off even by a light sprinkle of rain. I'm rating three stars because I found swirl marks in the paint. I'm not sure if it was from the cloth I used to remove the wax. It was a micro fiber towel which I just learned there are different qualities of micro fiber. I'm going to give this another try with a different towel to see if I have better results.

The super hot summer sun here in SC can literally "bake" a cars finish. I have been using #21 for three years now on my FX and BMW 335Ci with incredible results. EZ to apply and remove...lasts 6-8 months. I've recommended #21 to many friends - they LOVE IT!

I run kcdetailing.com and can say that I love this product. We use about 20 different types of waxes and sealants and this one works well for a lot of situations. Performs well. Best results when applied with a rotary buffer.

I applied #21 Sealant on my new 09 Ford F150 after washing and claying the surface. After 2 thin coats you will notice a deep gloss especially with darker colors. Very easy to apply and buff off with a micro fiber towel. One note: make sure to apply thin coats for the best application.

A new "Favorite"
March 23, 2009
Bought the M21 as an alternative to Klasse with the objective of easier application/removal. I'm NOT disappointed...this product is a breeze to use, even by hand, and the only reason I've not rated it "5Stars" is I can't vouch for durability yet. Great look on dark blue as well as metalliac silver.

Meguiars #21

One of the best products I've EVER used. It took me about 15 minutes to complete my car. 5 months later the water beads and the paint shines almost as much as the day I applied it.
