STEK has been our primary film supplier since the studio opened. Picking one PPF brand and standing behind it is a deliberate choice — it means our installers know exactly how the film stretches, where it crases on tight curves, and how the adhesive cures in the LA heat-cycle. After hundreds of full-body PPF jobs and several thousand window-tint installs, we have not switched. Why we picked STEK over XPEL and our DYNOshield vs DYNOmatte field review walk through the engineering reasons.
Who STEK is
STEK is a global manufacturer of high-grade urethane paint protection film and ceramic window tint, headquartered with US operations in Texas. The brand is best known for two product lines: clear self-healing PPF (DYNOshield) and satin/matte PPF (DYNOmatte) that became one of the dominant color-change layers in the luxury and exotic market. Their ceramic window film line, Smartfilm, hit the US market more recently and competes head-to-head with 3M Crystalline and XPEL Prime XR Plus.
Their factory cuts to OEM-vehicle templates by VIN — meaning we plotter-cut every panel before install, no razor blades on paint. The plotter library covers ~95% of cars we see in LA (Tesla, BMW, Mercedes, Audi, Porsche, Lamborghini, Range Rover, Cadillac, Lucid, Rivian, all current Cybertruck variants).
DYNOshield — clear PPF
DYNOshield is the clear, self-healing paint protection film line. Optical clarity is excellent — once installed and cured, the film is essentially invisible. The topcoat is hydrophobic and self-heals minor swirl marks under heat (LA sun does most of the work). 10-year manufacturer warranty against yellowing, cracking, and delamination.
Where DYNOshield wins specifically:
- Edge consistency — STEK plotter templates trim 2-3mm from panel edges, which keeps the wrap line tucked into the door gap rather than visible from 6 feet.
- Self-heal at LA dashboard temps — typical scratches from car-wash brushes vanish within 48 hours of normal sun exposure.
- Stretchability on compound curves — Porsche 911 GT3 rear quarter, BMW M3 fender flare, Cybertruck side trapezoid — DYNOshield's elasticity handles them all without fishmouth.
DYNOmatte — satin PPF
DYNOmatte does two jobs in one layer: protect the paint and change the finish from gloss to satin. It's a topcoat-modified PPF — same urethane base as DYNOshield but with a textured top layer that diffuses light into a clean satin sheen. 8-year manufacturer warranty.
This is the product that's been driving most of our luxury PPF jobs since 2023. Customers want their car to look matte black, matte grey, or matte AMG-grey without the cost and risk of a custom paint job. DYNOmatte gives them the look + the protection in a single install. Our full review with side-by-side warranty differences.
DYNOcolors — color PPF
DYNOcolors is the color-changing PPF range — full opaque color while keeping all the protection benefits of urethane PPF. Available in gloss and matte. The colors STEK does well: black, deep grey, gunmetal, midnight blue, and the murdered-out matte palette. Color stability is excellent (no color-shift over years like older color PPF brands).
Cost is meaningfully higher than DYNOshield because the pigment layer adds material cost. We typically install DYNOcolors on Teslas, Cybertrucks, and Range Rovers where the customer specifically wants a color change without committing to vinyl or full repaint.
Smartfilm — ceramic window film
STEK Smartfilm is the ceramic window tint line. Non-metallic ceramic chemistry — same generation as 3M Crystalline and XPEL Prime XR Plus. We install it on every tint job out of our LA studio. Performance numbers we measure on customer cars at install:
- Visible Light Transmission (VLT) — available 5%, 15%, 20%, 35%, 50%, 70%. The 70% is what we install on legal-front. The 20% on legal-rear.
- Total Solar Energy Rejection (TSER) — 60-70% on the 20% shade.
- Infrared rejection — 99% on the IR-selective Smartfilm grade.
- UV rejection — 99%+ on every shade.
- Signal interference — none (ceramic is non-conductive). GPS, LTE, AM/FM, key-fob, Tesla rear-glass antenna — all unaffected.
Color stability is the key reason we run Smartfilm: ceramic doesn't oxidize at LA dashboard temperatures. Six-year-old Smartfilm installs we've stripped for paint jobs measured within 1.5% of their original VLT spec.
STEK warranty — what it actually covers
STEK warranty registration goes through us as the Authorized Dealer. We file your VIN + install date + product line within 7 days of completion. The warranty stays with the vehicle (transferable on resale to one subsequent owner).
What it covers:
- Yellowing — covered for the warranty period (10-yr DYNOshield, 8-yr DYNOmatte/DYNOcolors).
- Cracking and delamination — covered.
- Bubbling at edges — covered if not caused by aftermarket modification or impact.
- Optical haze — covered.
What it does not cover: stone chip damage that penetrates the film (rare on highway driving, more common on construction-zone gravel), DIY removal damage, or modifications by another shop. Two warranty claims we've processed in five years — both replaced free of charge by STEK.
Why STEK over XPEL or Suntek
The question we get most from luxury-car owners before they book. Our take, after running both brands daily:
- STEK plotter library is broader than Suntek for current-year EVs (Cybertruck, Lucid Air, Rivian R1T variants). Suntek tends to lag 6-12 months on new model templates.
- STEK DYNOmatte is the dominant satin PPF in the LA luxury market. XPEL Stealth competes, but DYNOmatte's surface texture is closer to factory satin paint and we get fewer "looks too plasticky" comments.
- STEK pricing is competitive with XPEL Ultimate Plus at the dealer-tier level, and STEK warranty service has been faster in our experience.
- One brand across PPF + window film simplifies stocking, training, and warranty paperwork. Most shops carrying multiple PPF brands end up doing one of them poorly.

Frequently asked questions
Is STEK as good as XPEL?
For clear PPF, we consider them equivalent in optical clarity and warranty. Where STEK pulls ahead is in the satin/matte category (DYNOmatte vs Stealth) — we've installed both and DYNOmatte's surface texture reads closer to factory satin paint. Pricing at dealer-tier is comparable.
Is the STEK warranty transferable?
Yes — once. The original install warranty stays with the vehicle and transfers to one subsequent owner. We file paperwork with STEK at the time of resale; the new owner just needs the vehicle's VIN.
Can I install DYNOmatte over a DYNOshield install?
Yes, but it's a remove-and-redo. DYNOshield can be peeled cleanly (within ~5 years of install) and DYNOmatte applied fresh. Some customers do this when they've had clear PPF for years and want a finish change without paint work.
Does Smartfilm tint affect Tesla LTE / GPS?
No. Ceramic film is non-conductive — Tesla rear-glass antennas, GPS, LTE, key fob, Bluetooth all unaffected. The reception drop people experience with old metallized window film does not happen with Smartfilm.
What's the lead time on a DYNOmatte full body?
10-14 days install once material is sourced. We typically have DYNOmatte in the shade you want in stock. If the colorway requires a STEK custom order, add 5-7 days. Vehicle stays at the shop for the install duration; we arrange transport for high-end pickups in West LA.
