Sun film on the Swift: the 70 percent rule and what it leaves you with

Park my Sizzling Red nose out on a hot afternoon and the dash gets properly warm, so I plan shade before I plan breakfast. Which is how sun film ends up on my maybe list every summer.

The bit I had wrong for years is that film itself isn't banned. What's allowed is certified safety glazing, not the old blackout sheets. Garware's CMVR explainer lays it out: the windscreen and front glasses have to stay at 70 percent light transmission, rear sides at 50, and the film should carry IS 2553 (Part 2) 2019 marking. Their guide is here.

So the trade off is obvious. A compliant film looks almost clear, and you're buying heat and UV relief, not a dark cabin. Cheap unbranded rolls bubble and go purple fast, and anything darker is a roadside conversation you don't need.

I'm leaning ceramic on the sides and keeping cloth sunshades for the rear. Tell me what's on your glass and whether the installer showed you the certification.
