Quick and Easy!
At first I was worried about the product, read some of the reviews, applies the product and wow, super easy to apply and the shine is awesome. Applied after I cleaned the entire truck with the Blackfire cleaner and added some fresh wax, I will check back on the durability of the product, but so far very happy.
ProsSuper easy to apply, a little goes a long way.
ConsNone noted yet

Great Shine
This product has an easy to use application with a Shine that is as close to ceramic as you can get without the cost of ceramic. Used Blackfire prior to last weekend's car show and took first place. Would recommend using it by applying the spray onto a clean microfiber towel and not spraying directly onto the car. I'm also throwing away the microfiber towel when finished for fear the glass particles. May scratch the paint. Better safe than sorry.

Average for its class
After testing 12 different SiO2 sprays I found this one to be average. It lasts for around 2 weeks before it needs to be reapplied. Follow the directions and spray liberally onto the panel then spread with a product dampened microfiber towel. It did not streak and removed easy. There are better SiO2 sprays but at this price point it works just as well as the others in its class. I don't consider this a sealant but more of a coating topper to use after washing to maintain gloss. Works similar to the BF Coating Booster.
ProsNone
ConsLasts only 2 weeks on a daily driver

Great Product!
I recently shifted all my shop products over to the Black Fire line. I just received the SI02 spray sealant and have only had the chance to apply it to a BMW 540 that was in for an express maintenance detail last week. I had previously performed a two step detail in the Spring and finished with Wolfgang paint sealer. The SI02 is very easy to apply and buff. You just need to be very careful about spraying it on your microfiber towel and not the car to avoid overspray. It buffed to a beautiful gloss and should offer the customer an additional 3 months of protection. Good stuff!
ProsEasy to apply and buff!
ConsBe careful with overspray!

Easy on, Easy off
Tried it for the first time on my Ram daily driver. This was an easy sealant to put on. A couple sprays and spread out with a microfiber cloth. A little goes a very long way. Wait a minute or two and buff with a clean microfiber cloth. Really easy to buff and smooth. Nice shine. No streaking. Key is to use very little, less than a detail spray. Finish is glass smooth. Nice beading. I just hope it lasts in the FL sun and rain.

Cheaper SI02 Product
Goes on easy. Shine/gloss at least equal to machine application of hi-quality carnuba. Only been on a couple weeks, durability yet to be determined.

Blackfire Sio2 Spray sealant
This is the first time I have used a sealant. I usually use Mckees 37 100% carnuba wax. Used one of those "clay" pads as I washed the car. (car is new - '17 Equinox). Dried surface. Applied sealant. easy on, very difficult to remove. Once I finally got it removed & streak free, It took a lot of microfiber cloths & elbow grease, The finish is fantastic! I followed the directions on the container, watched the video, But removal was difficult on both cars. Used it on both daily drivers. My 07 Impala is silver, it now looks like it was freshly clear coated. It has its original paint & sits outside all the time, as does the Equinox, (classics are in the garage). I even used it on our new stove, around the burners, nothing sticks to it, makes cleanup a breeze.
ProsFantastic shine.
ConsDifficult removal

Leaves residue
Sitting outside my car had morning dew and this product left a residue under the dew. I would not recommend this if you leave your car outside.

Meh
I bought this without really reading or thinking about it enough. It is basically a sealant with a disappointing depth of shine despite full paint prep. It is quite easy to apply actually, since one can buff the excess off. If used sparingly, it takes very little time to do a whole car. The appearance of UPP, over which I layer Collinite, is awesome and lasts six months. I did not layer wax over this since I wanted to give it a fair trial and did not want to compromise the magical nanotechnology space-age skin that bonds to your paint by a process that cannot be explained to mere mortals. When it stops sheeting, which I suspect will be quite soon, I will try layering Collinite or Pinnacle over it and see how it looks and how long it lasts. The bottle I have will probably last for ten years since it takes very little to do a car. I am going to try it on other surfaces around the house and probably use the many other products I have that make my car really sparkle.

I see no difference from full synthetic paint sealants
To be honest, I feel like I just wasted $50 when I bought this. I don't see any improvement or difference in shine or paint feel compared to my usual full-synthetic paint sealants (Wolfgang, Rejex, etc.) Thsi product goes on easy, but it requires an extra step to buff off so It doesn't work as well as an after-wash quick detailer as do the spray-on synthetic sealants. It's not a bad product, but it's not worth the premium price. I'll stick with tried and true synthetics.

Extremely Hydrophobic
Super slick, extremely hydrophobic, and great shine. My only draw back would be its ease of use. Follow the instructions exactly as written. If you allow the product to sit on the paint it become extremely difficult to remove, especially on a black vehicle.

Perfection
After applying BLACKFIRE Carnauba wax I spray this sealant on a microfiber towel and go over the entire vehicle. WOW. I’m getting more compliments than ever.
ProsWorth it to me -Make my vehicles stand out. You get what you pay for.

Shine quality about normal, initial smoothness of finish superber.
Purchased this product and applied to a D/A polished and waxed black paint. It was very easy to apply as advertised and looked great. I wouldn't say I noticed a huge difference in the paint reflection or depth, but the first time I washed the car the microfiber drying towel literally sailed off the surface and it felt ultra smooth. I have only washed twice since the application so its durability of "months" is yet to be tested.
ProsEasy to apply Smooth finish Water beading qualities
ConsCost Durability not tested

Good but not as Expected
I am a big advocate for trying the next best thing and am always looking for the next "best product". I have used several Blackfire products and have loved them so my expectations were very high when purchasing this for the first time. Application is very easy and it goes on and wipes off very quickly. I have used similar SIO2 products from both Sonax and Adams and expected this to be at least as good, if not better. What is causing me to rate this a little lower is that I was expecting a high degree of glossiness and slickness and this did not achieve that. I will stick with those products once this is gone. It is a good detai spray for in between coatings but not to the standard I have come to expect with Blackfire.
ProsGoes on easy and wipes off easy Does not smear Durability seems to be pretty decent between washes
ConsNot as slick nor provide the gloss of other products with similar compounds.

Best spray wax/sealant i've used
I've used a number of spray on waxes/sealants and this is by far the best I've used yet. The product goes on easy, and seems to flash off in under 30 seconds. There is slight hazing once dry, and it is removed/buffed off with minimum effort. I've put the product through two washes and it seems to be quite long lasting, and at this point i'm not sure i'll ever bother with a 'real' wax/sealant again.
ProsEasy application Easy buff off Outstanding shine

Great product, absolute head turning results.
I have been a fan of Blackfire products for a while, again not disappointed but impressed with this new product. Exceptionally easy to use and delivers beyond expectations for a wipe on - wipe off product. If it is durable anything close to the shine and slickness it delivers then it will get a great big thumbs up.
ProsBeautiful shine and depth. Super easy to use. Makes dry down after a wash a snap, water just runs off.
ConsNone so far.

This product works as advertised. It put a beautiful glossy and slippery protective coating on my wife's 2012 Mineral Gray BMW X1 with relatively little effort. She couldn't be more pleased.
ProsResults Ease of use
ConsContains Silicon Dioxide nanoparticles. It is unclear how nanoparticles interact with the human body (skin and lung tissue). I personally wore gloves and a HEPA filter mask during the application of this product.

EASIEST TO APPLY AUTOMOBILE EXTERIOR COATING I HAVE EVER USED AND I'VE TRIED A LOT!
While I am a devoted car enthusiast and love keeping my cars in pristine condition, I hate actually doing the work. After washing and detailing cars at a car rental during my four years in college and washing a concrete mixer daily for thirty years, I don't enjoy the process. I am always looking for products that are easy to apply and offer longevity between application intervals. Autogeek regularly sends me alerts of new products that continue to evolve in ease of application and durability. The alert and application video for Blackfire SiO2 got my attention. As it was on a temporary, introductory sale, the risk of it joining my many other car products on my shelf was minimized. I bought it. As I still do not know if this product can be applied in the sun, I started on my garaged 2013 Inferno Orange Camaro. This product goes on easily and you use so little of it. As my five year old Camaro has only 7500 miles on it, the paint finish is in excellent shape and responded well to SiO2. The real test would be my ten year old, non-garaged deep ruby red Chevy Silverado sitting in my driveway. I love this 33,000 mile truck and have been showing it some love lately by having the hood, roof and fiberglass bed cover refinished to a high standard after the clear coat "gave up the ghost." I applied it in the sun when the surface was not overly hot to the touch and it appeared to work fine. You wipe it on and the "carrier" for the actual coating virtually evaporates leaving minimal residue to buff off. Both my new paint and the ten year old paint responded well. In addition, it simplified the tedious nature of coating a vehicle of this size. I will not know the duration of this product for some time as it was just applied but this morning I woke to a drizzly, almost rainy day and the micro-beading of the water was evident. Now on to my garaged Giallo Ferrari 355 Spider. It has excellent paint and should respond well to this product.

Great Product
I've always been afraid of using paint sealants because of the possibility of streaking the paint if not applied correctly. This product defies that notation. If you follow the easy instructions, the result is unbelievable. The paint is slick as glass (SiO2). After a month, the paint is still slick. I'll have to wait five more months to see if the protection lasts six month as prescribed. So far, I'm totally satisfied.
