RainX Windscreen Repair Kit
Discussion
Anybody used this ?
Driving along a recently " paved " stony road this morning at about 20mph. Idiot truckdriver was going well over the limit and ended up somehow flinging up a stone at my windscreen. I was on my way to a shopping centre so picked up some " RainX Windscreen Repair " resin type thing.
Watched all the YouTube tutorials etc before trying. Long story short, the tiny circular crack is now huge and now looks like half a spider. I now have to get the windscreen replaced. I don't feel comfy driving the car as if I even touch the cracks, or put the wipers on, it gets bigger.
Thankfully it is covered by my insurance. I do however now have a long one week wait without a car.
My opinion is if you get a crack/chip in the windscreen, dont use rainX.
I suppose the location didn't help, as it's bang on centre in the windscreen which is where I'd assume the weakest part is.

Not sure why you wouldn't immediately call out one of the windscreen repair people and let the professionals do it. Cracks got bigger as you've continued to drive it.
Even at the side of the road ? There was nowhere to pull over as it was a country lane. I literally drove straight back home.Ah well. Lesson learnt, won't mess with one next time !

Would it be wise to not drive the car at all now, until it's been replaced ?
I would not risk it, safer to park it upMakaveliX said:

No experience of the RainX product, but I've had 2 windscreen repairs done in the past on my insurance and both times they went like yours (which they had warned me could happen). I continued driving the car and new screen was installed the following week.Glassman (who knows about this stuff ;-)) has posted that lots of professionals also make a hash of perfectly repairable chips so I wouldn't feel too bad. It's the main reason I haven't bothered getting my current windscreen chip repaired.

so at that point it couldn't have been cracked. And you didn't literally drive straight home...
More holes in this story than the windscreen

From what I've seen of the RainX kit (I've got one unused) it's designed to fill a chip or a very small crack. I would imagine it's fairly limited in how much it can 'repair' a crack.
Not dig at you OP but I'm guessing the original crack in the screen was perhaps a bit too hefty for a DIY kit, maybe even for a pro to come out and repair.

I would not risk it, safer to park it upObviously if the crack spreads across your vision then it might be wise to stop driving it both for the fact its effecting what you can see and also the police may take a dim view of it.

The weakest part of the windscreen is the edge. Yours probably cracked because the glass was too warm (direct sunlight) and/or the repair jig was putting too much pressure on the break. My opinion is if you get a crack/chip in the windscreen, dont use rainX.

DIY repair kits might be 'okay' for simple repairs; but the instructions do not cover how to dry-out a break, or how to manipulate a complex one.
