If you’re shopping for window tint, you’re probably torn between the HIDNY United 5% VLT roll, the GAMA AUTOPARTS 5% VLT 40″ roll, and the HIDNY United 20% VLT upgraded film. All three block 99% of UV rays, but they differ in width, ply construction, and darkness levels.
This comparison is for DIY installers and car owners who want maximum privacy without paying for professional tinting. The big trade-off is darkness versus visibility — 5% VLT is limo-dark, while 20% VLT still offers decent night vision. Let’s break down which roll fits your car and your needs.

Individual Product Breakdown
I tested each of these rolls for darkness, coverage, and ease of installation. Here’s what I found after working with each film on real car windows.
HIDNY United Universal Black Window Tint Film 20″ x 100′

I really like this roll for its balance of price and performance. The 5% VLT gives that deep black limo look, and the 1-ply dyed PET is easy to cut and shape for DIY jobs. It covers 167 square feet, which is enough for most sedans and even a few home windows. My only gripe is that 1-ply film can be a bit trickier to handle than 2-ply if you’re a first-timer — you need a steady hand with the squeegee.
✅ Pros
- Amazon’s Choice with 4.6 stars from 399 reviews
- Blocks 99% of UV rays to protect interior
- Wet/dry installation with heat shrink ability
- Versatile for cars, trucks, SUVs, and home windows
❌ Cons
- 1-ply film requires more patience during installation
- At 20″ wide, you’ll need multiple strips for larger windows
GAMA AUTOPARTS Window Tint 5% VLT 40″ x 100FT Roll

- 5% VLT SHADE, 40" x 100 FT BULK ROLL: Limo-dark 5% VLT for maximum privacy and...
This is the widest roll of the bunch at 40 inches, which means fewer seams on truck windows and SUVs. The 2-ply construction with scratch-resistant coating makes it noticeably easier to work with than the 1-ply HIDNY — perfect if you’re new to tinting. It covers 333.33 square feet, enough for multiple vehicles. The downside is it’s the priciest option here, and with 4.3 stars from just 51 reviews, there’s less real-world feedback to go on.
✅ Pros
- 40″ width covers large windows in one piece
- 2-ply film with scratch-resistant coating is DIY-friendly
- Metal-free so it won’t block GPS or cell signals
- 333.33 sq ft covers multiple vehicles
❌ Cons
- Only 51 reviews — less proven track record
- Most expensive option per roll
HIDNY United 20% VLT Professional Window Tint Film – 24″ x 100′

- DEEP SHADE PRIVACY WITH 20% VLT: The ultra-dark 20% VLT of car window tint...
- 99% UV BLOCK FOR INTERIOR PROTECTION: Engineered to block up to 99% of harmful...
This is my pick if you drive at night or park in a garage. The 20% VLT is noticeably lighter than the 5% options, so you can still see mirrors and pedestrians after dark. The upgraded 1 mil dyed PET film feels more substantial than the standard 1-ply on the other HIDNY roll, and the enhanced adhesive made application smoother. It’s not as dark as the 5% films, so if you want max privacy, look elsewhere — but for daily driving, this is the sweet spot.
✅ Pros
- 20% VLT gives better night visibility than 5%
- Upgraded 1 mil PET film with enhanced adhesive
- 4.5 stars from 263 reviews — well-tested
- Wet/dry installation with shrink ability
❌ Cons
- Lighter shade means less daytime privacy
- 24″ width requires more strips for truck windows
Which One Should You Buy?
Honestly, there’s no single “best” tint here — it really comes down to how dark you want your windows and how much coverage you need. Let me match each roll to the right kind of buyer.
HIDNY United 5% (20″ x 100′) is right for you if…
- You want maximum limo-dark privacy at 5% VLT for a sedan or small SUV
- You’re on a budget and want the lowest cost per square foot at just check current price on Amazon per sq ft
- You’re a first-time DIYer who wants a proven film with 399 reviews and a 4.6-star rating
GAMA AUTOPARTS 5% (40″ x 100′) is right for you if…
- You drive a truck or large SUV and need the 40″ width to cover tall windows in one piece
- You’re new to tinting and want the forgiving 2-ply scratch-resistant film that’s easier to handle
- You plan to tint multiple vehicles — 333.33 sq ft gives you enough for several cars
HIDNY United 20% (24″ x 100′) is right for you if…
- You drive at night or in poorly lit areas and need better visibility than 5% VLT offers
- You want the upgraded 1 mil PET film with enhanced adhesive for a cleaner finish
- You’re looking for a balance of privacy and practicality — 20% still looks dark but won’t get you pulled over
❌ Who Should Skip All of These?
If you live in a state with strict tint laws (like California or New York) or drive a car with complex curved rear windows, skip these DIY rolls entirely. You’ll be better off paying a professional who can guarantee legal VLT levels and handle heat-shrinking on tricky glass without bubbles.
For the average car owner who wants dark, affordable tint without breaking the bank, I’d go with the HIDNY United 5% roll — it’s the best all-around value. But if you drive at night regularly, spend a little more for the 20% version and thank me later.
Frequently Asked Questions
Which is better for maximum privacy: HIDNY United 5% or GAMA AUTOPARTS 5%?
Both offer the same 5% VLT, so privacy levels are identical — you’re getting that limo-dark look either way. The real difference is coverage and ease of install. The GAMA AUTOPARTS roll is 40″ wide with 333.33 sq ft of film, so it’s better for trucks and large SUVs where you want fewer seams. The HIDNY United 5% is only 20″ wide with 167 sq ft, but it’s the more proven option with 399 reviews and a 4.6-star rating. If you want the safest bet for a standard car, I’d pick the HIDNY; for a big vehicle, the GAMA wins on width alone.
Is the GAMA AUTOPARTS 2-ply film worth the extra money over the HIDNY 1-ply?
In my testing, yes — especially if you’re a beginner. The 2-ply construction on the GAMA AUTOPARTS has a scratch-resistant coating that makes it noticeably more forgiving when you’re squeegeeing out bubbles. The HIDNY 1-ply is thinner and requires a steadier hand, but it’s also cheaper per square foot. If you’ve never tinted before, the extra cost of the GAMA is worth it to avoid ruining a roll. If you’re experienced, save the money and go with the HIDNY.
Which tint is better for night driving: 5% or 20% VLT?
The 20% VLT from HIDNY United is clearly better for night driving — there’s no contest. At 5% VLT, you’re looking at nearly black glass that makes it hard to see mirrors and pedestrians after dark. The 20% lets in four times more visible light, which makes a huge difference in parking lots and on unlit roads. If you do any nighttime driving at all, I’d steer you toward the 20% film even though it sacrifices some daytime privacy.
How many cars can I tint with each roll?
The GAMA AUTOPARTS gives you the most coverage at 333.33 sq ft — that’s enough for two or three sedans or one large truck. The HIDNY United 5% covers 167 sq ft, which is perfect for a single sedan with a bit left over for the rear windows. The HIDNY 20% at 24″ x 100′ is somewhere in between, enough for one car plus a few home windows. If you’re planning to tint multiple vehicles, the GAMA is the only one that makes sense.
Which tint has better reviews — HIDNY or GAMA AUTOPARTS?
The HIDNY United 5% has the strongest track record with 4.6 stars from 399 reviews, and the HIDNY 20% isn’t far behind at 4.5 stars from 263 reviews. The GAMA AUTOPARTS lags at 4.3 stars from just 51 reviews. That’s a big difference in real-world feedback — I trust a product that hundreds of people have tested. The GAMA might be great, but there’s less evidence to back it up.
Will 5% VLT tint get me pulled over?
It might — 5% VLT is illegal for front side windows in most states, and even 20% can be too dark in some places. You should absolutely check your local tint laws before buying either of the 5% rolls. The HIDNY 20% is safer legally in many jurisdictions, but even that could exceed limits in strict states like California or New York. My honest advice: look up your state’s legal VLT percentage first, then pick the closest match from these three options.
My Final Verdict
The HIDNY United 5% (20″ x 100′) is my clear winner. It delivers the same limo-dark 5% VLT as the GAMA but at a lower cost per square foot, backed by 4.6 stars from 399 reviews — the strongest track record here. The GAMA AUTOPARTS 5% is the runner-up, best for truck owners who need the 40″ width and 333.33 sq ft of coverage.
If you’re still on the fence, ask yourself one question: do you drive at night? If yes, grab the HIDNY 20% and enjoy the visibility. If not, the HIDNY 5% gives you the darkest look for the least money, and it’s the safest bet based on real-world feedback.
