Ceramic IM70

The Ceramic IM70 film from 3M offers a solid build with its nano-ceramic technology, ensuring it won't fade over time and won't mess with your GPS or phone signals. While it blocks 40% of the sun's heat, giving some relief, it's not the top performer in its class of lighter films. It does a decent job at reducing glare by 16%, though you might still notice some dashboard reflection, especially at night. The film excels in UV protection, blocking 99% of harmful rays to keep your skin and car interior safe. Every claim here is backed by 3M's own documentation, linked for you to verify before making a decision.

A light, clear-view film for SUV side and rear glass: 40% total solar energy rejection and 60% infrared rejection in a metal-free film that leaves GPS, FASTag and phone signal alone, plus 99% UV rejection to help protect the cabin from fading.

Most cabin heat arrives as infrared and visible light. Ceramic IM films use nano-ceramic particles, not metal, to reject infrared: 60% IRR (measured on the film alone) at 75% VLT. TSER, 40% here, is the broader figure: it counts the whole solar spectrum and is measured on glass, so real cars differ a little. A lighter film always rejects less total heat than a darker one, and the IM range trades heat rejection for clarity — IM70 sits at the clear end. Because the film is metal-free it does not interfere with GPS, FASTag or mobile signal.

It is the lightest tier, so heat rejection is modest: 40% TSER, lower than the darker IM tiers, and it gives little privacy. Choose a darker IM tier if heat or privacy is the priority. Tint limits vary by state, so check current rules before choosing a level.

Have it fitted by a professional installer — 3M specifies wet application only. Clean with a neutral, abrasive-free glass cleaner and a soft cloth, and avoid sticking tapes, suction cups or stickers on the film.
