Testimonials

Randy and Mika took their time and did a great job! They explained everything to me and made sure I was happy with everything before I left. They took great care of my car! Their space is Lake St. Louis is uniquely designed and easy to find. I will definitely be back for my windshield, and will be recommending to friends. Thank you Randy and Mika!

Just got my brand new Model 3 tinted at Marz and Randy knocked it out the park. The detail and meticulous work they put in was next level; every edge, every curve, perfect alignment, no bubbles, no bullshit. It looks clean as hell and turned out even better than I expected. Randy and his wife are incredible people too, made me feel right at home the whole time. Real genuine vibes, no upselling pressure, just good folks doing elite work. Their pricing smoked every major tint brand I checked; way more competitive for this quality. If you want your whip looking right, hit up Marz. Outstanding job from start to finish. Won’t go anywhere else. Highly recommend!

—Conner Begeman
Had a great experience with Marz Undefined. They got me in quick and knocked out two of my trucks with no issues at all. The tint came out super clean all around and the quality of work was top notch. Everything looks even and professional, and they were easy to work with from start to finish. Definitely recommend them if you want good work done fast and done right.

—Chris Torres
Wonderful job on my 2023 Honda Accord. Full tint with sunstrip. Its perfect. Very friendly owners. Very thorough. Even dropped my car off to me after completion. Above and beyond.
