Jescar Power Lock Plus Polymer Sealant
The sealant to buy if you want this done once a year
Tap any row for the full write-up. Prices come straight from Amazon and are never typed in by hand.
The verdict
Buy Jescar Power Lock Plus. It is the durability benchmark among consumer sealants — most of a year on a cared-for car — and it applies as easily as anything here. Chemical Guys JetSeal is the one to choose if you also want to seal wheels and trim, because it tolerates heat far better.
02
Why nobody recommends sealants, and why they should
A polymer sealant protects for four to eight months, applies in an hour with no cure conditions, works over uncorrected paint, and costs less than a coating. For a daily driver that is almost exactly the right product.
It is also unexciting, which is most of why it gets overlooked. Ceramic coatings are more interesting to write about and more profitable to sell; carnauba waxes are more pleasant to use and more photogenic. The sealant just quietly works, twice a year.

Jescar Power Lock Plus Polymer Sealant
Best for: The sealant to buy if you want this done once a year
Power Lock Plus is the durability benchmark among consumer sealants, and it applies as easily as anything here — thin coat, short cure, wipe off. If the goal is to protect a car properly and not think about it for six months, this is the product.
Who should skip it. Carnauba warmth. A polymer sealant looks sharp and glassy, and on dark paint some people genuinely prefer the softer carnauba look.

No — a sealant replaces a coating, it does not top one
JetSeal was developed for aerospace surfaces and it tolerates heat better than most paint sealants, which makes it genuinely useful on wheels and exhaust trim as well as paint. Durable, straightforward, and nothing clever about applying it.
Who should skip it. Looks. JetSeal protects well and does very little for gloss, so most people layer a wax or a spray on top of it.

What works
Tolerates heat, so it works on wheels and trim
Long durability claim backed by a long track record
Layers happily under a carnauba
What does not
Adds very little gloss on its own
Needs curing time before layering
Chemical Guys does not publish a cure time we could verify
Deep Gloss is the sealant that most convincingly imitates a carnauba look while lasting like a polymer. If the choice between the two has been bothering you, this is the product that makes it mostly go away.
Who should skip it. Budget buyers. It is the most expensive sealant here, and the gloss advantage over Power Lock is real but not enormous.

845 is a carnauba and polymer hybrid originally formulated for electrical insulators, and it is the most durable thing in this roundup that still calls itself a wax. Six months outdoors is realistic where a pure carnauba manages six weeks.
Who should skip it. Anyone chasing the deepest carnauba glow. 845 looks good rather than spectacular, and it is thin and runny out of the bottle, which takes getting used to.

01Clean, bare paint. Wash, and decontaminate if it has been more than six months. A sealant bonds to the clear coat, so anything in between is what it bonds to instead.
02Thin and even. Sealants are thinner than wax and much easier to over-apply, which makes removal unpleasant and does not improve durability.
03A [foam or microfiber applicator](/protection/best-applicator-pads), in overlapping passes, one panel at a time.
04Wait for the haze, typically 10 to 20 minutes depending on the product and the temperature.
05Remove with a clean plush towel, turning to fresh sides constantly.
06Leave it 12 hours before the car gets wet, and before layering anything on top.

Where a sealant is the wrong choice
On a ceramic coated car, where a sealant sits on top and mutes the coating. Use an SiO2 spray.
If you want maximum depth on black paint, where a carnauba genuinely looks better. See the wax roundup.
If you are about to correct the paint. Polish first, then seal.
On a show car that gets detailed weekly, where the durability advantage buys you nothing you would notice.

Questions people actually ask
What is the best paint sealant for cars?
Jescar Power Lock Plus for outright durability — most of a year on a cared-for car — applied as easily as anything in the category. Chemical Guys JetSeal if you also want to seal wheels and trim, where its heat tolerance matters.
How long does a paint sealant last?
Four to eight months on a car that is washed with a pH-neutral shampoo and not run through brush washes. Less on a car parked outside year-round. The beading test tells you where you stand better than any calendar.
Can you put wax over a sealant?
Yes, and it is a sensible combination. Let the sealant cure for about 12 hours first, then the sealant does the protecting and the carnauba adds warmth on top. Applying the wax too early interferes with the sealant bonding properly.
Is a sealant better than a ceramic coating?
For most daily drivers, better suited. It gives most of the practical benefit for an hour of work and no cure conditions, over paint that does not need correcting first. A coating lasts far longer and demands far more before it will.
