True High-Performance Products
At Cornerstone, we don’t just install film — we install the 𝗯𝗲𝘀𝘁 in the industry. We exclusively use Autobahn Films for automotive services and Hüper Optik for residential and commercial flat glass. Both brands are engineered for top-tier performance and backed by the strongest warranties available.
Autobahn Paint Protection Film (PPF)
- Features a ceramic-coated top layer— a premium feature rarely included unless you’re paying extra.
- Backed by the only true lifetime warranty in the industry (most PPFs only offer 10 years).
- Includes a one-time accidental no-fault warranty that credits up to $250 per incident — even if the damage was your fault. No other brand offers this level of coverage.
Autobahn i3+ Automotive Window Film:
- The highest heat-rejecting automotive film in the industry.
- Protected by a full lifetime warranty and supported nationwide.
- Includes a $75 accidental no-fault warranty toward replacement in case of accidental damage.
Custom-Installed, Hand-Finished Edges
For paint protection film (PPF), we don’t just rely on basic plotter patterns. Our experienced computer pattern design team custom-modifies our patterns to provide maximum surface protection, creating a seamless, nearly invisible finish that protects better and looks cleaner. We also take the time to remove and reapply emblems/badges to prevent unsightly cut-outs. It’s time-consuming. It’s meticulous. But it’s how premium installs should be done.

Quality Control Obsession
We’ve documented countless examples of bad installs — visible seams, jagged cuts, dirt under film, and even rear windows tinted in strips. We want you to be informed, because education is important with this type of service.

WALL OF SHAME:
The Risk of Cutting Corners
Unfortunately, not all shops are created equal. In a crowded market, some shops try to win your business with low prices — but that savings comes at a high cost.
Too often, we see:
- Cheap, re-boxed or Chinese white-labeled films disguised as premium brands. We call it the "bait-and-switch" tactic. The customer is sold a "premium" paint protection film that they visually can't tell if it's good or bad, only to get damaged — and once we remove the film we find it's super thin (4mil vs the standard 8mil thickness).
- Busy shops focused on quantity, not quality, rushing installs and leaving behind bubbles, contamination, lifting edges — and even damaged/cut paint.
- Pre-cut, cookie-cutter patterns used without any custom modification. These often leave visible seams, exposed edges, and inadequate coverage of vulnerable surfaces.
- Wrong films installed — like dyed tint instead of ceramic — leaving customers with fading, poor heat rejection, or interior damage.
- Zero post-install care or warranty registration, leaving you on your own when something goes wrong.
- Sub-contracted labor at other shops — Yes, we've seen it. You bring your car to a shop expecting the installation to be done there, and they drive it to another location without your knowledge to have the work done.
Customers deserve better.
We Respect Your Time & Experience
Getting premium protection shouldn’t feel like a hassle. That’s why we offer amenities designed for busy professionals and discerning clients:
- Complimentary Uber rides while your vehicle is being serviced
- After-hours pickup with secure key drop and lockbox access
- Clean, comfortable customer lounge with Wi-Fi and refreshments
- Text updates and support throughout your install
- Real warranty support and post-install care
Trusted. Transparent. Top Rated
We’re proud to be one of the most highly reviewed tint and PPF shops in the United States let alone the Kansas City area. Our customers include exotic vehicle owners, luxury car dealers, local families, and professionals who simply want it done right — the first time. Customers have even shipped their vehicles to us from multiple states away via enclosed trailer because they trust our work that much.
Make the Smarter Choice
Film might look the same on the surface — but what's underneath is what truly matters. The company. The installer. The product. The method. The mindset.
Don’t roll the dice on your home or vehicle. Choose a shop that stands behind its work and treats your property like their own.
