Quintessential™ takes quinclorac performance to the next level and is an excellent choice if you are going after crabgrass that has invaded your lawn. This is a selective, post-emergent herbicide that can be safely applied to many types of turf to control a variety of broadleaf and grassy weeds, including crabgrass, foxtail, signal grass, and torpedo grass.

  • Up to 90-day control for both broadleaf and grassy weeds
  • Active Ingredients is Dimethylamine salt of Quinclorac 18.92%
  • Unique, patent-pending formulation powered by H-Value Technology, a proprietary performance additive that increases efficacy
  • Great for controlling crabgrass, including the mid-tiller stage of growth
  • Available in multiple sizes *

Product Description:

Quintessential alters the formulation of quinclorac in a way that improves the absorption of the product into the plant. That means faster activity and higher rate load in the targeted weed, as well as improved performance in drought stress or rainfast situations. And unlike any other herbicide on the market, Quintessential demonstrates improved control of crabgrass at all growth stages, including the problematic 3-5 tiller stage.

This product can be applied to both residential and non-residential turf. Selective control means it doesn’t harm turf.

Quintessential can be applied from seven days prior to seeding and up to twenty-eight days after selected weeds have emerged. The use of methylated seed oil, such as Duo Stick Select is recommended to enhance the effectiveness of the product. If you cannot get methylated seed oil, a non-ionic surfactant can be used.

Target pests include Barnyardgrass, Black medic, Foxtails, Clover, Crabgrass (large & smooth), Daisy, Dandelion, Morningglory, Wild Violet, and more.

Highly Recommend – Amazing Results on My Honda Accords!
Size: 1 Count (Pack of 1), Size: 1 Count (Pack of 1)
I recently used the Cerakote Headlight Restoration Kit on both my 2008 and 2014 Honda Accords, and I’m genuinely impressed. The headlights on both cars were badly oxidized, hazy, and yellowed from years of sun exposure. After following the kit’s instructions, they look crystal clear and almost like new again. The process is pretty straightforward and beginner-friendly. It does take roughly an hour per headlight set if you follow all the steps carefully and allow proper air drying time before the final clear coat. There’s a bit of elbow grease involved with the sanding and polishing stages, but nothing overly difficult. The kit provides everything you need, and the instructions are clear. The results are excellent! Both cars now have headlights that look factory-fresh. I’m really happy with how bright and clear they are at night. Best part? I saved a ton of money by restoring them instead of buying expensive OEM replacements. The only minor uncertainty is long-term durability (how well the clear coat holds up after a couple years of sun, weather, and car washes), but for the price and the dramatic improvement I saw, it’s absolutely worth it. I’d definitely buy this kit again if needed. Highly recommended for anyone dealing with cloudy headlights. Great product that delivers professional-looking results at a fraction of the cost!

Best product I've tried so far but still temporary. YMMV.
Size: 1 Count (Pack of 1)
This product really does work. It is the best I've used. I purchased in September 2024 and am writing this review in May of 2026, roughly one year and 8 months later. I noticed product failure a little after a year after application and it has been degrading slowly since. Currently the product is visible like a layer of clear paint flaking off and you can physically scratch some off. Here are the pros and cons. Pros: Clarity, relative ease of use, value Cons: Taping and sanding, doesn't last for as long as you own your car as claimed Best used as a temporary fix. Bottom line, would I use it again? Yes. What am I doing today? Replacing the headlights completely. Why? I plan on keeping my car for longer than a year.

Review After Using on 3 Different Cars over 3 years
Size: 1 Count (Pack of 1)
Cerakote Headlight Restoration Kit : After Using on 3 Different Cars over 3 years This is my second time purchasing the Cerakote Headlight Restoration Kit, and I’ve now used it across three different vehicles. At this point, I feel comfortable saying this product genuinely works when used correctly. Before trying this kit, I considered replacing my headlights entirely. The cheapest replacement set I found was around $150 just for the parts. Installation would have required removing the grille, bumper, and other components, which adds time and complexity. For an older vehicle, that didn’t make financial sense. Instead, I chose to restore the original headlights. Cost and Value My first package cost me $17, and I restored two cars with that single kit ( about 9$ per pair). That alone made it worth it. For under $20: I restored two separate vehicles Avoided buying new headlight assemblies Avoided removing the bumper and grille Compared to a $150+ replacement plus labor, the savings are significant. Durability 1 year+ under direct Cali sunlight (currently on year 2 and still good) First Car – Learning the Process The first time I used the kit, my results were decent but not perfect. That was mainly because I didn’t fully understand how sanding and polishing actually work. ( this reoxidized fastest under 8 months, but it was mostly my fault) I didn’t initially realize: The headlight needs to stay wet during sanding Oxidation must be completely removed before applying clear coat Even pressure matters/ 50% overlap coverage when appling ceramic Once I understood that sanding is the most important step, everything improved. Second Car (beater) Major Improvement The second vehicle was heavily oxidized and yellowed. I used the remaining material from that same $17 kit and restored it completely. The clarity difference was dramatic. It looked close to factory condition, and night visibility noticeably improved. That was when I realized the product itself is solid; the key is proper technique. Third Car ; Recent purchase By the third car, the process felt straightforward. I followed the instructions carefully, kept the surface wet while sanding, and applied the clear coat evenly in one smooth pass. The final result was clear, glossy, and uniform. No haze, no streaking. Durability On my first vehicle, the restoration lasted close to a year perfectly( I sold that car this year and it still had clear headlights), and that car was parked outside in direct sun most days. For a DIY kit at this price point, that level of durability is impressive. Final Thoughts I seriously considered spending $150 on replacement headlights( this was cheapest ) and dealing with removing body panels. Instead, I spent $17 and restored two cars. Now having used it on three vehicles, I can say this kit is effective, cost-efficient, and worth the time if you follow the process properly. It does require effort and patience, but the results justify it. I would purchase it again.

works as advertised!
Size: 1 Count (Pack of 1)
I purchased this kit to renew the headlights on my 2016 Nissan Frontier pick-up. The headlights had become slightly oxidized and dull -- not that bad but it was bothering me and for the price of the kit I figured it was worth the effort to attempt to renew them. All I can say is -- WOW, what a difference. The end result looked like new -- clean, brilliant and bright. Read the directions (2 or 3 times) and follow them EXACTLY. Total time for me from opening the kit to being done was about 2 hours and I was taking my time. This kit is different in that the final step applies a UV resistant coating which really makes the glass super transparent. Great investment in the time and money. I can't stop admiring my new (old) headlights!

Incredible Results! The "Z-Line" is Back!
Size: 1 Count (Pack of 1), Size: 1 Count (Pack of 1)
I’ve tried a few "wipe-on" fixes in the past, but the CERAKOTE® Ceramic Headlight Restoration Kit is in a completely different league. If you are tired of hazy, yellowed lenses and weak nighttime visibility, look no further. 📖 Instructions & Ease of Use The first thing that stood out was the clarity of the instructions. The kit breaks everything down into a simple, step-by-step process. Even if you aren't a "car person," the directions are foolproof. They don't just tell you what to do; they explain why each step matters, which gave me the confidence to get the job done right the first time. ✨ Restoration Effectiveness As you can see in my Before and After photos, the transformation is night and day. My headlights went from a dull, oxidized yellow to a factory-fresh, crystal-clear finish. It didn't just "clean" them—it completely rejuvenated the plastic. 🔦 The Real Test: Light Output & Beam Pattern The most impressive part isn't just how the car looks, but how it performs at night. I’ve included a photo of my car parked against a wall in the dark to show the comparison: Passenger Side (Restored): You can see a sharp, distinct cutoff line and the perfect "Z-line" pattern. The light is focused exactly where it needs to be on the road. Driver Side (Not Restored yet): The light is completely distorted. There is no cutoff, just a messy blob of light that scatters everywhere, likely blinding oncoming traffic while providing less actual visibility for me. Final Verdict This kit doesn't just make your car look better; it’s a genuine safety upgrade. Seeing that crisp Z-line back on the wall proves that the clarity is internal as well as external. Highly recommended!
