About RennSpec
One Detailer.
One Standard.
Your Driveway.
RennSpec Auto Concierge is a Gyeon Certified mobile detailing studio built around luxury, exotic and enthusiast vehicles across the greater Los Angeles area.
The Owner
Landon Dennis
Landon started RennSpec after years of watching good cars get worse at the hands of volume shops — swirls buried under glaze, trim baked out by the SoCal sun, interiors wiped down instead of actually cleaned. The fix was not a better wash. It was a process: assess the paint honestly, correct it with the least aggressive method that achieves a flawless finish, then lock the result in behind a professional ceramic coating.
That process is why RennSpec carries Gyeon Certified installer credentials and works exclusively with Gyeon Pro products. Paint depth is measured, a test section is finished before the rest of the panel, and every job is completed under proper lighting so defects get removed rather than temporarily hidden.
The business is intentionally mobile. Clients in Calabasas, Malibu and the West Valley do not have days to give up to a shop queue, so RennSpec brings the studio to the driveway — self-contained power and water, one detailer, start to finish.
What Makes It Different
Gyeon Certified Installer
Gyeon Pro coatings are sold only to certified installers. That means documented chemistry, real durability ratings and a finish that can be stood behind — not a mystery bottle bought off a shelf.
Owner-Performed Work
The person who quotes the job is the person who does it. No rotating crew, no handing a six-figure car to whoever is on shift that afternoon.
Fully Mobile, Fully Self-Contained
We arrive with our own power and water and work at your home or office. Nothing is required from you except a parking space.
