I have used several types of coatings, including ceramic on our cars. I thought I would give Blackfire a try. I have used Blackfire SiO2 Sealant on two cars so far and overall results are amazing. The application was too easy and quick I immediately thought this sealant can't be good. I was wrong. After 12 hours or so the finish cures to a deep deep glossy shine. The one car was driven in steady rain and after the water dried the car looked like it had just been washed! I can't speak to the durability of the sealant but I don't think it really matters. Blackfire SiO2 is so easy to apply I looked forward to using it every 3 months or so! I will buy it again.
Pros1. Extremely easy to apply and buff. No streaks! 2. It can be used on glass and trim. 3. A little goes a LONG way.
Cons1. Not really a Con but there's no way to know the true durability. To be fair I'm guessing at most 3 months protection.

easy application
October 27, 2019
I tried out on the boat and that's an ideal application for this, beyond cars/trucks. Less precleaning of gelcoat and hydrophobic is great for water shedding. Looks good and very quick to do... I should've used on vehicles by now but weather hasn't cooperated. Wasn't as effective on the colored plastic as the hybrid wax. Had to clean/rub more there but looks good on it. I think you should use latex gloves from what the label says and keep the rags separate as they shed water so well. I don't think they can be washed normally and don't want this on other fabrics. Eg: I rinsed off the micro towel I used and ran through the wringer and the water made large pea size beads, towel as almost dry. I'd used some soap, too. ps: A friend had recommended to me.
ConsTowel management and PPE (maybe) required. A little pricey.

Incredible Product
October 17, 2019
I bought this to see if it would do what it said it can do for your paint. After washing and using the clay bar, I applied the SiO2 to the paint. It went on easy and came off easy. The car benefited from two coats. After I did the Acura, the wife said we have a new car. She ran her hands over the finish and remarked how smooth the paint felt. You want to run your hand over the paint. After 24 hours the paint really pops and feels like glass. This is now a product I will keep in my stock of finishing supplies.
ProsEasy on and easy off.

Very Good Sealant
August 24, 2019
If you are looking for a siO2 sealant this is a very good one. I think The Autogeek house brands Blackfire, Pinnacle and Mckee's are formulated to make things easy as possible for the user. This sealant is another example, super easy to use. I just applied it to a clean car like a spray wax and I could see a huge jump in gloss which seemed better the next day. The water beading is insane and well over a week later and my car doesn't want to get dirty, nothing sticks to it.
ProsEasy to use and it has a nice look to it when it's on the car
ConsMight not be able to look at your paint in the bright sun

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
May 2, 2019
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.

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!

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.

Blackfire Sio2 Spray sealant
August 18, 2018
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

Extremely Hydrophobic
June 20, 2018
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.

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.
May 25, 2018
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

Best spray wax/sealant i've used
May 20, 2018
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

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.

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.

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.
