Yep. It's the real deal but you have to understand what it is and what it isn't.
C-Bond I is what you'll get for cars. Historically, window tint is applied using soapy water (I'm simplifying). C-Bond I is an additive that increases the effective strength of the glass and tint barrier. But understand - it's maybe 2:1, meaning 100% better, but still, that buys a little time - not a complete solution.
C-Bond II is the bulletproof stuff that requires an anchoring system. Intended for commercial and residential - not practical for cars yet.
Google for the YouTube video at Extreme Autowerks for an example of C-Bond applied to the shop's front door and the number of baseball bat strikes from the owner, staff and customers before the door gave in. I don't remember if that was C-Bond I or C-Bond II.
You can get C-Bond I applied to just the rear triangle windows for not a lot of money if you've already got tint applied to the car and don't want to redo all of it.
C-Bond also makes an effective exterior windshield coating with a good warranty. I picked up 2 stars in my windshield for the 2nd car (new front end is a bit of a rock magnet for windshields) in the first 6 weeks of ownership, learned of the C-Bond product thereafter, and in the almost 2 years since, have picked up zero additional stars. Anecdotal? Sure. Sample size of 1. But from where I sit, tens of thousands of miles later, it was money well spent.
Glad to see others picking up the C-Bond torch.
Now, additives aside, I also had the alarm enhancement installed a couple of weeks ago. It's nifty and yeah, it works. Remember to disable it before taking a nap in yer chariots, folks. Totally unobtrusive and imo should have been standard equipment in the States from Day One.
Two sets of dashcams for near-360 degree coverage (do compare the 4K versus the latest non-4K model specifically with regard to night vision/clarity before buying), a 24/7 mobile hotspot for cloud storage (see the ZTE Mobley or Skyroam's Solis orange hockey puck) C-Bond, and the alarm enhancement for glass breakage and tilt monitoring. Best solution I can figure at this juncture.
Yeah, locking mechanisms to secure the trunk better would be a whole lot easier, but given that it took 6 years to get glass breakage monitoring in the States, I'm not holding my breath.
