Mountainside Auto Refinement & Mobile Detailing

09/14/2026

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! 🚘🏆

Safe to say Sunday’s food situation is going to be handled 😮‍💨

Pretty fired up to have Fanwich joining us this Sunday for Greatest Day in Motorsports after seeing them back at Ball Arena again for AVS Alley.

They’ll be on site all day during the Indy 500 + Coca-Cola 600 watch party serving food while we’ve got the races on the projector, cars outside, simulator challenge, giveaways, and the shop open to the community.

May 24 is shaping up to be a really good day.

We have been invited back to Ball Arena for the AVS ALLEY watch party Wednesday for the big game! We will be featuring “The Hat-Trick Fries” again so don’t miss out!
