A New Jersey legal-style aftermarket tint setup on a four-door sedan leaves the windshield and front driver and passenger windows factory/untreated while tinting the windows behind the driver. The real 2017 Alfa Romeo Giulia shown in this guide has 5% ceramic tint on the rear doors, rear quarter windows and back window, with no aftermarket tint on the front doors or windshield.**

This is an actual Dope Tintings customer vehicle, not a stock photo or hypothetical example.

The customer specifically wanted to follow New Jersey's normal window-tint rules, reduce his chances of tint-related police attention and provide more privacy, UV protection and some heat rejection for his children riding in the back.

The finished result also demonstrates something important:

A legal-style sedan tint setup in New Jersey does not necessarily have to look evenly matched from front to rear.

For this customer's 2017 Alfa Romeo Giulia, we installed 5% ceramic window tint on:

• Both rear door windows
• Both rear quarter windows
• The back window

We intentionally left the following glass without aftermarket film:

• Driver-side front window
• Passenger-side front window
• Windshield

The result is an obvious lighter front to darker rear contrast.

That was intentional.

This customer wasn't trying to make every window match. His priority was keeping the front glass untreated while getting substantial privacy for his children in the rear.

For the complete statewide rules behind this configuration, read our New Jersey Window Tint Laws: Complete 2026 Guide.

For the normal legal-style configuration we're demonstrating here, think of the sedan in two sections.

Front of the vehicle: windshield and front driver/passenger windows.

Behind the driver: rear side windows, quarter windows where applicable and rear glass.

New Jersey restricts add-on sunscreening on the windshield and front side windows outside applicable exemptions. NJMVC specifically maintains a medical-exemption process for qualifying windshield and front-side sunscreening.

Windows behind the driver are treated differently. New Jersey courts have also specifically recognized that rear-window tint is not treated the same as front windshield/front-side tint.

For this Giulia, that means the customer's aftermarket film begins with the rear doors and continues toward the back of the sedan.

No.

5% is not what makes this particular configuration a legal-style setup.

The important distinction is where the aftermarket film is installed.

This customer personally chose 5% because he wanted substantial rear privacy for his children.

Another sedan owner could choose:

• 35%
• 20%
• 15%
• 5%

on eligible rear glass depending on the appearance, privacy and nighttime visibility they want.

At Dope Tintings, customers tinting only the rear portion of a sedan commonly lean toward 20%, 15% or 5%.

For the average customer who wants privacy for children without making the rear extremely dark, my personal recommendation is usually:

20% on the rear doors, quarter windows and back window.

It creates a very noticeable contrast.

The front portion of this Alfa Romeo remained light because the front doors and windshield were left without aftermarket film.

Starting at the rear doors, the vehicle becomes dramatically darker because of the 5% film.

I would not describe this setup as perfectly balanced from front to rear.

It isn't supposed to be.

It's a good example of what happens when the customer's priority is keeping the front glass untreated while still getting substantial privacy behind the driver.

On this Alfa Romeo, 5% provided the privacy the customer wanted.

The photos were taken on a cloudy, rainy day, which made the rear cabin appear especially dark from outside.

Lighting always matters when judging window tint.

On a bright sunny day, someone standing very close to the rear glass may be able to see somewhat into the vehicle.

From approximately 5 to 10 feet away, however, 5% provides substantial privacy in our experience.

That's another reason you shouldn't judge a tint percentage from one photograph alone.

It can be.

We explained that tradeoff to this customer before installation.

5% provides excellent privacy from outside, but the same darkness can make it harder for the driver to see through the rear side windows and back glass at night.

That becomes more noticeable:

• On roads without streetlights
• During heavy rain
• While backing up
• In dark parking areas
• In poorly illuminated neighborhoods

The customer understood that tradeoff. His biggest priority was protecting the children riding in the rear.

The customer wanted UV protection, some heat rejection and privacy for his children and specifically requested ceramic film.

We explained that ceramic is primarily a high heat-rejection film and that maximum cabin-wide heat performance requires thinking about all of the major glass areas.

Because he was only treating the rear portion of the vehicle, we explained that carbon would have been a more economical option for his particular situation.

He still wanted ceramic.

We educated him about the options and installed what he chose.

That's how we approach these conversations at Dope Tintings: give the customer our professional recommendation, explain the tradeoffs and let the customer make the final decision.

For a complete comparison, read What Is the Difference Between Carbon and Ceramic Window Tint?.

For many customers, yes.

If you're only tinting the rear passenger area and want good heat rejection without paying ceramic pricing, carbon can make a lot of sense.

If your only concern is appearance and privacy, standard film may also accomplish what you need.

That's why we don't automatically recommend ceramic simply because it's the most expensive option.

We first ask:

What do you want the film to do for you?

There are very light ceramic films that can provide heat and UV performance without creating the appearance of extremely dark glass.

However, this is important:

A light or clear-looking ceramic film is still aftermarket film.

Putting 70% ceramic on a front side window does not automatically make the installation compliant with New Jersey's normal front-window rules simply because the film looks clear.

If your number-one priority is following the normal rules without relying on an exemption, the simplest approach is the one shown on this Alfa Romeo:

Leave the front doors and windshield factory/untreated.

Don't assume that putting a lighter film such as 35% on the front doors makes it legal.

We've had customers believe:

"As long as police can see me, I'll be fine."

We've also had customers tell us they were stopped with lighter aftermarket film on their front windows, including 35% and even 50%.

A lighter percentage may attract less attention than something extremely dark, but less noticeable does not mean legally equivalent to leaving the glass untreated.

If a customer tells me:

"I want to follow New Jersey's normal rules, protect my kids and have some privacy, but I don't want the back ridiculously dark,"

my recommendation would usually be:

20% on the rear doors, rear quarter windows and back window.

For film type, I'd normally recommend standard or carbon, depending on whether heat rejection is important.

I'd leave the front driver/passenger windows and windshield factory/untreated if minimizing tint-related legal concerns is the customer's number-one priority.

5% isn't necessary.

It was simply what this particular Alfa Romeo customer wanted.

No.

That's probably the biggest visual lesson from this Giulia.

Some customers want a smooth appearance from front to rear.

Others prioritize following the front-window rules.

Those goals can produce very different-looking vehicles.

We've had sedan customers choose:

• Clear factory fronts with dark rears
• 35% fronts with 15% or 20% rears for a gradual contrast
• The same percentage throughout for a uniform appearance

Those are customer choices we've encountered—not a statement that every configuration complies with New Jersey law.

The Giulia shown here represents the customer who said:

"Leave my fronts alone. I want privacy for my kids in the back."

A normal legal-style setup leaves the windshield and front driver/passenger windows without aftermarket film while tinting eligible glass behind the driver. The Alfa Romeo Giulia shown here uses 5% ceramic on the rear doors, quarter windows and back glass.

Very dark film can be used on eligible rear glass under New Jersey's rules. The applicable vehicle and rear-visibility requirements still matter.

No. You can choose a lighter rear percentage based on your privacy and visibility goals. 20%, 15% and 5% are common rear-only choices among our customers.

Don't assume 35% aftermarket film makes the front side windows legal in New Jersey. Front-side sunscreening is subject to New Jersey's restrictions and medical-exemption process.

For an average sedan customer wanting privacy for children without going extremely dark, our recommendation is often 20% standard or carbon on the eligible rear glass.

Not necessarily. Ceramic provides higher heat-rejection performance, but carbon can be a strong lower-cost option for customers only treating the rear passenger area.
