Meguiar’s keep clear headlight clear coat
Overall Best
Meguiar’s consistently hits the mark with some of my top car detailing products, and their headlight clear coats are no exception.
Their Keep Clear headlight clear coat serves as a restoration tool for hazy, yellowed headlights, while also working as a protective shield for new headlights, warding off tarnish over time.
As a consumer, I found this headlight clear coat to be top-notch. I used it to restore my old, weary headlights and was delighted by the outcome: a clear, glossy finish that elevated the overall aesthetics of my car.
One of the highlights from my personal testing was that this clear coat retained its shine and gloss, promising a polished, glass-like appearance for months, maybe even years. A bonus was the UV protection offered by Meguiar’s specific compounds, ideal for my car that spends most of its time parked outdoors.
This UV shield ensures that my headlights resist yellowing even under prolonged exposure to sunlight.
And this isn’t just a product for the worn and weary. This clear coat is also a perfect match for new headlights. It applies a protective layer, resisting wear and minimizing those tiny scratches that eventually steal the sparkle from your headlights.
While applying some clear coats can be a tedious task, Meguiar’s has made it straightforward with an easy-to-use aerosol can. This means you don’t need to be a professional detailer to achieve the best results. The inclusion of user-friendly instructions was a boon, ensuring an error-free application of the clear coat.
Pros
- Glossy finish
- UV protection
- Provides scratch resistance
- Ideal for restoring old headlights
- Resists yellowing
- Protects new headlights
- Easy to apply aerosol form
Cons
- May require re-application after a year
3M Quick Headlight Clear Coat
Best Budget
If you’re on the lookout for a budget-friendly clear coat, 3M’s Quick Headlight Clear Coat is the way to go. I found that it provides a simple yet glossy clear coat that performs impressively well on plastic headlight lenses.
It comes in a comprehensive package, equipped with everything necessary for a successful at-home clear coat application, absolutely hassle-free.
3M’s kit is tailor-made for car headlights and comes with bonus items like masking tape, light sanding discs, and protectant wax, adding immense value to your purchase. Normally, these are essentials you’d have to shell out for separately, so I really value 3M’s thoughtfulness in including them with the clear coat.
This particular concoction is crafted to tackle minor blurriness and surface degradation. It’s a handy solution for headlights showing minor wear, but I noticed it struggles with heavily yellowed and hazy headlights. Still, considering its price tag, few clear coats can compete with its efficacy.
Even with these limitations, I believe this is a splendid option for anyone wanting to safeguard their new car’s headlights without draining their wallet. The final finish is glossy enough to freshen up your headlights and amp up their aesthetic appeal.
Pros
- Easy to apply
- Glossy finish
- Budget friendly
- Package includes all necessary items
- Ideal for headlights on newer cars
- Works best with plastic lenses
- Adds abrasion resistance
- Prevents micro scratches
USC SprayMax 2K high gloss clear coat
Premium Choice
If it wasn’t for the heftier price tag, USC’s SprayMax 2K would have easily topped my list as the ultimate car headlight clear coat. This clear coat is a glossy, versatile wonder that just amps up the sparkle and sheen of your headlights.
I found it pretty straightforward to use, and it gifted my headlights with additional protection and superior resistance to abrasion.
What makes this clear coat stand out is its longevity. While my tests gave me immediate results, I’ve heard from many users that the SprayMax clear coat consistently lasted more than a year for each application. During this span, it sustains a thick, good-looking layer that not only enhances the look but also defends your headlights.
When I applied SprayMax to my old, worn-out headlights, the transformation in terms of shine was astounding. After cleaning the headlights, I sprayed even coatings of this aerosol-style clear coat and was rewarded with the most lustrous and reflective finish among all the clear coats I’ve tested.
This glossy finish doesn’t just look impressive, it’s incredibly resilient to scratches and road debris, effectively shielding your headlights from abrasive particles that could potentially damage them over time.
However, be warned – high-quality clear coats can be a bit tricky for novices. Heavier compounds like SprayMax, when not applied correctly, can lead to an “orange peel” effect where the compound accumulates in certain spots and peels off patchily.
But in my experience, the aerosol was effortless to apply evenly and accurately, giving you the gloss of multiple coats minus the mess of an uneven application. Interestingly, I found this particular clear coat meshed extremely well with the best headlight bulbs.
Lastly, a word of caution when handling this clear coat: always use safety gear (masks, goggles, gloves, etc) during application. SprayMax is a potent compound emitting significant vapors that could be harmful. I highly recommend applying it in an open-air environment.
Pros
- Glossiest finish
- Adds abrasion resistance
- Great for protecting new headlights
- Works well for restoring headlights
- Multi-purpose, works for most surfaces
