Meguiar's Keep Clear Headlight Coating, 4 Oz

I’ve struggled with foggy, yellowed headlights on my aging daily driver for years, and after trying multiple cheap coating products that faded in just a few months, Meguiar's Keep Clear Headlight Coating has completely exceeded my expectations. This 4-ounce aerosol formula is incredibly user-friendly for beginner DIYers like me, with no complicated mixing or professional tools required. I first polished my headlights thoroughly to remove old oxidation and grime, then applied two light, even coats of this coating following the official instructions. The spray nozzle delivers a fine, consistent mist that glides smoothly over headlight lenses, leaving zero streaks, drips, or uneven patches. It dries quickly without turning cloudy or sticky, forming a clear, invisible protective film instantly. What impresses me most is its reliable UV-blocking performance. My car sits outdoors full-time under direct sunlight and harsh weather, yet my restored headlights have stayed crystal clear with no yellowing or fading for nearly a full year. Unlike flimsy generic coatings that peel or wear off after rain washes, this formula adheres tightly to plastic lenses and resists daily wear, road grime, and extreme temperature changes. The compact aerosol can is easy to store in my garage for future touch-ups. It breathes new life into both restored and brand-new headlights, preserving bright illumination for safer night driving. Worth every penny, this is my new go-to headlight protection product for all my vehicles!

Meguiar's Keep Clear 4oz aerosol headlight coating is so straightforward to apply. I used it right after polishing my cloudy headlights, and it leaves a smooth, clear protective film. The UV blocking formula works well to slow oxidation and yellowing, promising up to one year of protection. It won’t fix deep scratches, but it’s perfect for locking in restored clarity. The can was sealed and arrived safely. Fast shipping and excellent results. Great maintenance product to preserve your headlights’ brightness.

Tonight I tried this Meguiar’s headlight coating after my 12‑hour shift. I got it because my 2010 Corolla lenses were getting hazy and I was too tired to deal with full sanding kits. Spray goes on fine and dries pretty quick. I like that I can wipe off small drips before they set and it does give the lights a cleaner look. Drove to my night shift yesterday and the beams looked a bit sharper 👍. I was hoping for a bigger jump in clarity though. It’s better, just not like new. Also the smell is strong so I had to do it in the open parking lot, which is annoying when you just want to go inside and sleep 😅.

Bringing my beat-up 12 year old hatchback back to “decent” is a constant grind, but this headlight coating helps a lot. I grabbed it after wet-sanding and polishing because i was tired of the lenses turning yellow again. I shake the can, do two quick passes, and that’s it. No streaks, which surprised me. Drove home from a late shift in heavy rain and the beams looked whiter and clearer, and i wasn’t squinting the whole way. Only downside, the shine fades a bit after a few weeks, so I’ll probably be respraying now and then.

I bought this coating because the headlights on my work SUV had started looking cloudy, and I use that vehicle for supply runs and late trips home from the shop. I do not have time to fuss with car upkeep, so the aerosol format appealed to me. I washed and dried the lenses first, then sprayed a light coat on them outside when I had a few minutes between customers. It went on without much mess, and I could finish the job quickly. The lenses looked clearer once everything dried, especially when I pulled out before opening the shop the next morning. That was the moment I felt glad I bought it, because I could see the road signs better without stopping to wipe the headlights again. I still plan to check them as the seasons change rather than assume one application handles every condition. The can is small enough to keep on a shelf in my garage, and I like that I can refresh the lenses myself instead of making another appointment. For a busy week, that is a useful bit of upkeep.

This product is easy to use and it’s 100% the best out there. I made sure before using the product that the headlights were clean. I also sprayed evenly side to side so that there would be no streaks while waiting for it to dry. I was skeptical at first as I’ve tried everything else but nothing is comparable to this product. It’s almost been a year and since I’ve did the process on my 2015 Nissan Rogue and the headlight cover still looks brand new. I’ve saved a lot of money as the replacement from dealership was over 1,200 dollars for each because they don’t sell just the cover. I am extremely satisfied and would recommend it to anyone that needs to get them headlight looking like new without breaking the bank. This product is for plastic headlight covers only.

Gave Meguiar’s coating a try. I had a headlight with some scuffing but no fading. Prepped it with 400, 500, and 600 grit wet sanding. Got the scuffs out and removed all the old coating. Followed the instructions and sprayed three coats. Got some fisheyes, so I wet-sanded with 1000, 2000, and 3000 grit. Then cut with heavy compound, polished, and waxed. Came out okay, but not great. The clear coat has some fogginess to it. Pros: It’s cheap Very accurate, consistent nozzle and spray pattern No leakage Easy to use Cons: Coating doesn’t level/liquefy well on the surface Not crisp and clear — has a foggy finish Tips: Shake very well. When finished, shake even more. Overall, it’s fine for an older car. I wouldn’t use it on newer-model headlight.

I grabbed this after seeing a mom on Instagram fix her cloudy headlights during nap time, so I figured I could handle it too. It goes on fast and my van lights look clearer, which helps on late grocery runs. I do wish it lasted longer though. Mine started fading after a few months. Still, it makes touch-ups pretty quick 🙂

The product did a great job of finishing off the headlight restoration. After using various sanding grades, the clear coat brought the headlights back to a clear shine. I found this much easier to use than a paint-on or wipe-on clear coat. The result was as excellent with no streaks.

J’ai commencé par polir les phares avec un chiffon et le produit « Fine scratch remover 2 » de Novus acheté sur Amazon (bouteille rouge et blanche). J’ai par la suite appliqué deux couches du produit « Headlight coating » de Maguiar’s pour protéger les phares. Il ne reste qu’à voir combien de temps les phares vont demeurer clair! Ça m’a littéralement pris 20 minutes pour arriver à ce résultat puisque le plastique des phares n’était pas brisé ou grafigné en profondeur, seulement jaunie.

Great

Excelente 👌

This is a clear coat, uv protection spray. You first have to sand and polish your headlights if they are faded/dull. Use only one coat, not two for clearer results. All headlights eventually fade due to sun damage.
