Test setup

Same parking spot, full sun, 1pm, July–August in Vista. Cabin temps measured with an IR thermometer at dashboard, steering wheel, and seat.

Before ceramic tint (factory glass)

• Dashboard: 162°F
• Steering wheel: 148°F
• Black leather seat: 152°F
• Cabin air: 124°F

After 70% front + 20% rear ceramic + clear ceramic windshield

• Dashboard: 138°F (-24°F)
• Steering wheel: 124°F (-24°F)
• Black leather seat: 130°F (-22°F)
• Cabin air: 106°F (-18°F)

What this means

• AC reaches comfortable temp in 2–3 minutes instead of 8–10
• EV range improvement: 4–7% in summer
• Your interior stops fading
• The car is genuinely usable after 30 minutes parked

ROI

Ceramic tint pays for itself in saved AC fuel/range and protected interior in under 2 years.

What to do

1. Pick a legal shade (front 70%, rear unrestricted) 2. Use only adhesive-safe ceramic film 3. Keep your install warranty paperwork

At lease end

• Schedule professional removal 1–2 weeks before turn-in
• Pro removal leaves zero adhesive residue
• Cost: $80–$180 depending on vehicle

What NOT to do

• Don't peel it yourself — you'll rip defrost lines and pay big
• Don't ignore bubbles or damage hoping the dealer won't notice — they will

What we offer

A "lease-end removal" credit when you book new tint with us.

What it is

Slip solution — water + a tiny amount of mild surfactant — gets sandwiched between the film and the glass during install. It evaporates out through the film's adhesive over the first week.

How long it lasts

• Hot, sunny days: 2–4 days
• Cool, overcast days: 5–10 days
• Direct garage parking, AC off: longer

How to speed it up

• Park in the sun with windows up
• Crack windows occasionally for airflow
• Don't roll windows all the way down for 3–5 days

When to worry

If the smell persists past 14 days or smells strongly of ammonia, call us.

Window tint

Goes on glass. Blocks UV, IR (heat), and visible light. Adds privacy. Lifetime warranty on premium ceramic.

Paint Protection Film (PPF)

Goes on paint. Self-healing clear urethane film that absorbs rock chips, sand, bug acid, and minor scratches. Common areas: front bumper, hood, fenders, mirrors.

Ceramic coating

A chemical sealant on paint — adds gloss and beads water but does NOT stop rock chips. It's a complement to PPF, not a replacement.

What we install

Coastal Tint focuses on window tint — automotive film, ceramic windshield, windshield strips. We can refer you to a trusted PPF specialist.

When you need both

New car owners who want long-term protection usually get PPF on impact zones + ceramic tint on all glass.

Normal — water haze (week 1–4)

Tiny pinhead bubbles or a milky haze. This is trapped install solution evaporating through the film. It clears completely on its own. Don't poke it. Don't roll the window down.

Normal — minor edge texture

A faint wavy line within 1mm of the edge. It's the film's adhesive lay-down line. Not a defect.

Not normal — large bubbles after 30 days

If bubbles bigger than a pencil eraser remain after a month, that's a defect. Adhesive failure or contamination during install.

Not normal — peeling edges

Edges should be sealed and invisible. If you can lift them with a fingernail, that's a defect.

What to do

Take photos. Call us. We come to you, inspect, and re-shoot the panel under warranty — no charge.

Why ceramic only

Rivian's glass is heavily heat-loaded by design. Anything less than ceramic is a waste of money.

Recommended package

• Front sides: 70% Ceramic (CA legal)
• Rear sides: 20% Ceramic
• Rear hatch glass: 20% Ceramic
• Panoramic roof: Ceramic — drops cabin heat 20°F+

Common questions

• Will it affect sensors? No — ceramic is signal-safe.
• Roof glass cracks if I tint it? No, our ceramic film is approved for panoramic glass.
• OTA updates? Unaffected.

What we charge

• R1T full vehicle ceramic: $529
• R1S full vehicle ceramic + roof: $649

Mobile install in your driveway. 3 hours.

The glass roof problem

Both cars have huge panoramic glass roofs. They already include some UV/IR protection from the factory — but on a hot day, you'll still feel the heat. Adding a clear ceramic film cuts cabin temps dramatically without darkening it.

Best package for a Tesla

• **20% ceramic** on rear sides + rear window (matches the dark "blacked out" look)
• **Clear ceramic** on front side windows (legal + heat reduction)
• **Clear ceramic** on the glass roof (game-changer for heat)
• **Optional:** Clear ceramic on full windshield

Pricing for a Tesla

Model 3 and Y both fall in the sedan price range. Glass roof tinting is an add-on — usually $179–$249 depending on film.

Why ceramic specifically on Teslas

Carbon and dyed films can interfere with the cellular antennas embedded in some Tesla glass. Ceramic is signal-safe, so your phone, GPS, and OTA updates keep working perfectly.

What tint blocks

Any modern automotive film — dyed, carbon, or ceramic — blocks 99% of UV-A and UV-B. That's the same as SPF 1000.

You don't need dark tint

A 70% clear ceramic film up front blocks 99% UV. You don't have to go to limo black to protect your kids.

What we recommend for parents

• Clear ceramic on the windshield (99% UV, 60% heat rejection)
• Legal 70% ceramic on front sides
• 20–35% ceramic on rear sides (where the car seat lives)

Skin Cancer Foundation

Both the Skin Cancer Foundation and the AAD recommend automotive window film for daily UV exposure reduction.

First 3–4 days

• **Don't roll your windows down** — the film hasn't bonded yet
• A little hazing or water spotting is normal — that's the curing adhesive
• Don't try to clean it. Leave it alone.

First 30 days

• Avoid washing the inside of your windows
• Keep stuff away from the film (no suction-cup phone holders on tinted glass)
• Park in shade when possible — heat speeds curing but excessive UV can warp early

Cleaning forever after

• Use ammonia-free glass cleaner (regular Windex contains ammonia and will damage the film)
• Microfiber cloth only — paper towels can micro-scratch
• Spray the cloth, not the window

Red flags

If you see persistent bubbles, peeling, or purpling **after 30 days**, that's a defect — call your installer for a warranty claim. Coastal Tint backs every install with a lifetime warranty, no questions asked.

Why DIY usually fails

The film is two layers — the top peels off easily, leaving a stubborn adhesive layer behind. People scrape with razors and rip out defroster grid lines on the rear glass. A new defroster grid is $$$$.

The pro method

Steam + slow peel. We use a steamer to soften the adhesive, lift the entire film in big sheets, then chemical-strip remaining residue. Defroster lines stay intact.

What it costs

• Sedan: $80–$120 removal
• Truck/SUV: $120–$180
• Tesla Model 3/Y: $100–$150

When you book a re-tint with us, removal pricing drops 40–50% as a package.

When to remove

• Purple haze (UV-faded dyed film)
• Bubbles or peeling edges
• Cracking film
• You want a different shade

Why ceramic is non-negotiable on big rigs

Dyed film on an F-150 or Tahoe is a waste of money. The cabin heat soak is brutal in summer — only ceramic IR rejection actually keeps the second and third rows comfortable.

Recommended specs

• Front (legal): 70% Ceramic
• Rear sides: 20% Ceramic
• Rear glass / liftgate: 5–20% Ceramic
• Sunroof: Ceramic film if not factory privacy glass

Vehicles we've tinted recently

F-150, Silverado, Tundra, Tahoe, Suburban, 4Runner, Bronco, Wrangler, Rivian R1S, Cybertruck, Model X, Telluride, Palisade.

Pricing for trucks/SUVs

Carbon: from $329 · Ceramic: from $499 · Add panoramic roof from $89.

Mobile install in 3 hours. We come to you.

Mobile install — what's good

• We come to your driveway, office, or apartment garage
• No half-day waiting in a shop lobby
• Same quality install if you pick a real pro (not a side-hustle)
• Usually cheaper because we don't pay shop overhead

Mobile install — what to watch for

• Need flat, shaded space (driveway, garage, covered carport works)
• Wind/dust matters — a clean garage is ideal
• Make sure the installer carries lifetime warranty paperwork

Shop install — what's good

• Climate-controlled, dust-free environment
• Some shops have specialty tools for rare cars
• Easier for windshield ceramic on certain vehicles

Shop install — what to watch for

• Drop-off + pickup wastes a day
• Higher prices to cover shop rent
• Often booked out 1–2 weeks

Which to pick

For 95% of vehicles, mobile is just as clean and far more convenient. For really rare cars or full windshield work, a shop sometimes makes sense. Either way, ask about lifetime warranty.

What's legal

• A non-reflective sun strip across the **top 4 inches**
• A **70%+ VLT** clear ceramic film across the entire windshield
• 99% UV block (free)

What's illegal

• Anything darker than 70% VLT on the windshield
• Mirrored or metallic finishes

Why ceramic windshield tint is worth $249

• Cabin temps drop 15–25°F on hot days
• Steering wheel stops being a branding iron
• AC works less, you get better range/MPG
• UV protection saves your dash from fading

What it looks like

Crystal clear. You cannot tell it's there. No tint cops will ever pull you over for it.

Booking

Add a full ceramic windshield to any tint package — we install it onsite in 45 minutes.

VLT explained

VLT (visible light transmission) = how much light passes through. Lower number = darker tint.

• **5% (limo)** — Almost black. Hard to see out at night.
• **20%** — Dark and aggressive. Most popular choice.
• **35%** — Medium. Good privacy + visibility balance.
• **50%** — Light. Mostly heat rejection, minimal darkening.

What I recommend for North County SD

• **Daily driver:** 20% rear (legal everywhere) + clear ceramic up front
• **Family SUV:** 35% rear for visibility + clear ceramic up front
• **Show car / blacked out look:** 5% rear + clear ceramic up front
• **Coastal driver, sunsets matter:** 35% rear so you can see at golden hour

Why darker isn't always better

5% looks killer in photos. Less great when you're backing out of a dark parking garage at night. Test by sitting in a friend's car with that shade before you commit.

5% (Limo)

Total privacy. You can barely see in. Common on rear glass for luxury sedans and SUVs. California-legal on rear sides & back glass.

20%

Dark but you can still see passengers in good light. Most popular shade for rear glass on daily drivers.

35%

Medium tint — looks "factory plus." Good balance of style and visibility. Very popular on Tesla Model 3 and Y rear glass.

50%

Light tint. From outside it barely looks tinted at all but you still get serious heat & UV protection. The legal ceramic option for front side windows is usually 70% — even lighter than this.

What we recommend

Most North County customers go with 70% ceramic up front (legal heat rejection) + 20% or 35% on the rear. It looks great and stays California-legal.

Dyed film

The cheapest option. A pigment dye absorbs sunlight. Looks great when new, but fades to purple in a few years and offers minimal heat rejection.

• **Heat rejection:** ~30–40%
• **UV block:** Yes (99%)
• **Fade resistance:** Poor (2–4 years)
• **Price:** From $189 sedan

Carbon film

Uses carbon particles instead of dye. Won't fade, looks darker and richer, and rejects more heat than dyed.

• **Heat rejection:** ~40–50%
• **UV block:** Yes (99%)
• **Fade resistance:** Excellent (lifetime)
• **Price:** From $279 sedan

Ceramic film

The premium option. Uses ceramic nanoparticles that block infrared heat without darkening the glass. The best for hot climates like San Diego.

• **Heat rejection:** ~60–75% (and 90%+ infrared)
• **UV block:** Yes (99%)
• **Fade resistance:** Excellent (lifetime)
• **Signal-friendly:** Won't block GPS or phone signals
• **Price:** From $429 sedan

Which should you get?

For most North County drivers, **ceramic is worth the upgrade**. The heat difference on a hot day is dramatic, and you won't replace it again. Carbon is the budget pick if you want something that lasts. Dyed only makes sense for short-term ownership.

What a real warranty covers

• Bubbling
• Peeling
• Cracking
• Fading or color change (purple)
• Adhesive failure
• Demetallization (for metallic films)

What it doesn't cover

• Damage from abrasive cleaning
• Glass breakage (not the film's fault)
• Defrost line damage from peeling tint yourself
• Cuts or scratches from objects

"Lifetime of the vehicle" vs "lifetime of the owner"

Big difference. Premium ceramic warranties usually transfer to a new owner if you sell the car. Cheap film warranties die the second you sign over the title.

Manufacturer vs installer

The manufacturer warrants the film. The installer warrants the install (bubbles from poor application, lifted edges). You want both.

How we handle it

Coastal Tint installs only manufacturer-warrantied film and stands behind every install for life. If anything goes wrong — we come to you and fix it.

Front side windows

Must allow at least **70% VLT** (visible light transmission). That means you can put a film on, but only a very light one — usually a clear ceramic film for heat rejection.

Rear side windows

**Any darkness is allowed.** 5%, 20%, 35%, 50% — your call.

Rear (back) window

**Any darkness is allowed**, same as rear sides.

Windshield

You can put a non-reflective sun strip across the **top 4 inches** of the windshield. Or a full clear ceramic film for heat rejection that doesn't reduce VLT.

Reflectivity

No mirror or metallic finish that's more reflective than a standard window.

Medical exemption

If you have a documented medical condition (lupus, severe photosensitivity, etc.) you can apply for a CA Highway Patrol exemption to legally tint your front side windows darker.

What happens if you get pulled over

A "fix-it" ticket — usually $25–$197 plus the cost to remove the tint. Repeat offenses get more expensive.

How we keep you legal

We help every customer pick a legal combination — usually a clear ceramic film up front for heat rejection, plus your shade of choice in the rear. Book a free consultation and we'll walk you through it.

VLT — Visible Light Transmission

The percentage of visible light passing through. 35% VLT = 35% light gets in, 65% blocked. Lower = darker.

TSER — Total Solar Energy Rejected

The headline number. Combines visible light, IR, and UV blocking into one figure. Premium ceramic hits 50–65% TSER. Anything claiming 80%+ is marketing fluff — physics doesn't allow it on auto glass.

IRR — Infrared Rejection

The number you actually feel. IR is the heat. A film with 90%+ IRR at peak wavelengths feels dramatically cooler than dyed film at the same shade.

UV Block

Should always be 99%+ on any modern film, ceramic or not. UV is what fades your interior and damages skin.

How to compare honestly

Ask for TSER and IRR at 950nm. If a shop only quotes "heat rejection %", they're hiding behind a vague metric. Real ceramic films publish full spectral data.
