I found the film from grab-gard.com is really the only way I could stop broken windshields. Where I live, my jeep friends constantly are getting broken windshields without the film. With the film, it seems to be saving us money.
Interesting, glad it is working out for you.
I've been using a different brand that my ppf installer recommended that I try. It's a single layer, but thicker. He seemed to think it was the brand that lasts the longest, so I figured I'd give it a shot. I'm at about 10 months and I don't see any...
You're not kidding. They seem so fragile. I broke my first windshield within weeks of delivery. I put this film onto mine and it seems to be working well to protect it: https://www.grab-gard.com/products/jeep-wrangler-windshield
I'd say you're seeing better than average for your setup. Driving habits also makes huge different. 75 mph on the freeway is going to really suck it down compared to 60. Plus 75mph with a lift and big tires kind of scares me.
My PPF guy suggested I use this one:
I've been really happy with it. It's supposedly more scratch resistant according to him. So far so good.
I'd second the tazer. It's not foolproof since they can find it and remove it, but the typical car thief wants to get in and out, to my understanding. So when it doesn't work, they'll just move on to a different one.
That is brutal. I have protection film on mine to hopefully avoid the pain of replacing at that cost! I bought it here: https://www.grab-gard.com/products/jeep-wrangler-windshield
I've got a lot of miles on it at this point and it's holding up good.
Its been about 7 months now. Still happy with this film. I have had a few rocks hit really hard that I thought were going to break the windshield. Two of them left little dings in the film that you can see from the outside, but I don't really notice from the inside unless I'm looking for them...
