Car Window Tinting Redwood City

Quality automotive film works on the parts of sunlight you feel rather than only the light you see. A well-chosen Kepler film can reduce solar heat build-up, cut glare on bright afternoons and block ultraviolet light that fades and dries trim, leather and dashboards over time. Darker shades also make the cabin less inviting to look into when the car is parked. The right balance between visible light and heat performance depends on the film and shade you choose, so compare them side by side with your installer.

Kepler automotive films are built for long service, with a scratch-resistant coating on the exposed side to help them stand up to everyday cleaning and window movement. Film life in practice also depends on the glazing, the installation and how the car is cared for. Your installer can explain the coverage that applies to the film you choose. See our window tinting page for more on the range.

The film you choose is the biggest factor in cost. Kepler's standard, IR and IR+ nano-ceramic ranges offer different levels of solar heat performance, and each is available in a range of shades. Vehicle size and the number of windows also affect the job. Very cheap work often means lesser material or rushed fitting, and removing and redoing tint costs more than choosing carefully the first time. Ask your dealer what each range delivers before deciding. See our indicative car window tinting prices.

Start with the look you want, then match it to the performance you need. Visible light transmission describes how much light passes through the glass; it is separate from how much solar heat a film rejects, so a lighter shade in a higher range can outperform a darker basic film. Compare the exact film and shade rather than the percentage alone, and view the shades against your own glass where you can. Browse our car films to find the right fit, or check the tint percentages for a quick summary.

Car window tinting is legal, but the rules covering which windows may be tinted and how dark they may be are set by state law and are worth checking before you book. Our window tint laws page explains what the regulations cover. Choosing a film and meeting the rules are two separate steps, so confirm the current requirements with your installer and with California state law as well.

Old tint can be removed, but it needs patience. Careless removal risks scratching the glass or damaging demister lines on a rear screen, and adhesive left behind is difficult to clear. Our guide walks through the process step by step for anyone tackling it themselves, though many owners prefer to have removal handled at the same time as a new film is fitted.

Kepler films are built in layers, each with a job to do. Visible light is only part of the story: infrared heat and ultraviolet energy are invisible, yet they are what makes a parked car uncomfortable and what fades interiors over time. Our nano-ceramic IR and IR+ ranges are engineered to target that unseen part of the spectrum, so you get useful solar heat performance and UV protection without having to go as dark as you might expect.

Fitting window film does not normally affect a vehicle's factory warranty, since the film is applied to the inside surface of the glass rather than to any mechanical or electrical component. Policies vary between manufacturers and dealerships, so if you have any doubt it is worth confirming with your dealer before the work is booked.

New film needs a short settling period. Leave the windows up for the first days as advised by your installer, and expect a little haze or a few small water pockets while the film cures. After that, clean with a soft cloth or microfiber and a gentle, ammonia-free cleaner, and keep abrasive pads and scrapers away from the glass. Our care guide has the full detail here.
