A garage mishap changed the protection plan for this 2026 BMW Z4. 🛡️

We originally installed full-front paint protection film and a ceramic coating on this Z4. About a week later, the owner accidentally scratched a rear quarter panel in her garage and decided she wanted PPF on the rest of the vehicle, too.

On her next visit, we polished away the existing ceramic coating from the panels receiving film, installed STEK DYNOshield on the remaining body panels, and applied a fresh ceramic coating. We also tinted all the windows to complete the package.

Now, her Z4 has full-body PPF coverage—including the doors and rear quarters that weren’t part of the original installation.

Ceramic coating helps make cleaning and maintenance easier, while PPF adds a physical protective layer over the paint. Together, they’re a great combination for a car you want to enjoy and keep looking its best.

Considering full-front or full-body PPF? Send us a message—we’ll help you choose coverage that fits how you drive, park, and care for your vehicle.

Keeping this Lucid Gravity looking its best, mile after mile. ⚡

We protected the full front end with STEK DYNOshield paint protection film to help defend against rock chips and road debris while letting that beautiful finish shine through.

When we chose a film brand for our shop, STEK was the clear choice. The film quality and exceptional clarity stood out, and we’re proud to offer that same quality to our clients.

DYNOshield carries a 10-year manufacturer’s limited warranty. We also applied STEK’s Final Coat ceramic coating for added water repellency and easier maintenance—extending the PPF’s warranty to 12 years.

To complete the package, we tinted the two front windows with STEK SMARTseries ceramic film for added privacy, heat rejection, and comfort.

A beautiful vehicle deserves thoughtful protection. If you’re considering PPF, ceramic coating, or window tint, send us a message and we’ll help you choose the right combination for yours.

This G63 didn’t need more shine. It needed the right protection. 🏔️

This brand-new Mercedes-AMG G63 came to Mountainside for a protection package tailored to its matte finish, with just as much attention given to the details you don’t see.

We protected the full front end with STEK DYNOmatte paint protection film to complement the matte finish, and added STEK windshield protection film to the exterior glass.

Inside, STEK NEX+series ceramic tint went on every window—including the windshield and sunroof—for exceptional heat rejection and a more comfortable cabin. Interior ceramic coating and PPF on the infotainment screen rounded out the interior protection.

We also removed the wheels to ceramic coat the inner barrels and brake calipers. Those satin wheels deserve attention beyond the faces, and making brake-dust cleanup easier was a priority.

The exterior received STEK Final Coat ceramic coating for added protection and easier maintenance. Paired with the DYNOmatte installation, Final Coat extends the STEK PPF’s manufacturer warranty from 10 to 12 years with proper warranty registration.

From the sunroof to the wheel barrels, this was about more than looking good for the camera. It was about making a beautiful vehicle easier to enjoy and care for.

What a great day to be in Downtown Castle Rock! ☀️🚗

The streets are filling up with nearly 350 incredible classic cars as the Vintage Car Club of Castle Rock's annual car show gets underway this morning. We're honored to be hosting registration, check-in, and judging inside the Mountainside Auto Refinement lobby today as these beautiful vehicles take over downtown.

If you're looking for something fun to do this morning, come walk the show, support local businesses, and check out some truly amazing cars.

While you're here, be sure to stop by and see our friend Dave Lowry with Lowry Insurance, whose booth is located across from Z'Abbracci's Italian Restaurant. Dave is currently running a special giveaway where anyone who reaches out for an insurance quote to see if he can save you money, improve your coverage, or both will be entered to win a **$1,000 gift certificate to Mountainside Auto Refinement!**

Good luck to everyone entered, and thank you to the organizers, volunteers, participants, and local businesses who make events like this possible.

See you downtown! 🚘🏆
