Windshield Chips

Got the car hand washed today and the guys showed me some chips in my windshield. Not 1, but 3. This is the first time I've had this problem with any car. Have others noticed this.

Check with Speedy Auto Glass -- invisible fill-ins. They claim.

I've had my MS for 2 months and already have multiple chips on the windshield. Too soon to tell if it's just bad luck or if the windshield is more susceptible to this damage than my previous cars...

The chips I have a relative small - not the big "stars" - can these really be filled in?

It's best to tend to any chip on the windshield as quickly as possible.

I got a large chip that still shows even after being filled in. I was surprised to have gotten it. The windshield is tilted back much more then other cars I've owned, and I initially thought it would be harder to get chips as it more easily deflects the objects, but in fact maybe it more easily chips as the objects "dig out" a chuck of the glass.

You must be a mind reader. I live in the Chicago area and have never had a problem with chips on my windshield yet I too have multiple chips (very tiny more like nicks) in fact I can only see them when the sun hits my windshield. I did notice them for the first time when I got my car handwashed! I think they are too small to fill in.

Same here - let's call them knicks - and not chips - small enough to be noticeable when the light is at a certain angle - but usually not noticeable in most lighting.

The aftermarket cyanoacrylate windshield repair kits work great on these little chips and some "star" chips. The repair kit has a liquid holder that suction cups to the windshield with a grommet to hold the liquid in place over the affected area. You pour in about 6 drops of the liquid and place the plunger in and turn it down to get the liquid to squeeze out into the chipped area. Let it set in direct sun light (the liquid is activated by the UV rays of the sun) remove the aparatus and place a small patch (clear plactic) over the affected area until it finishes curing. Then you peel the plactic off and scrape down the area until all the excess hardened liquid is removed.

We've done this on our other vehicles and never had a problem passing inspections or have the area propogate into a long crack.

I meant: (clear plastic)...

I have one chip, and it was a big rock that got thrown up, so I am sure that any windshield wouldn't have done better. I took it to the Tesla-recommended place, and initially it was clear (you could detect some distortion), but overnight it became very noticeable. I'll leave it for now, but I may wind up replacing the windshield anyway.

Note that the heat shield coating complicates the repair.

Hmm, I think it's normal. I used to get lots of chips on my old car too. I do a lot of highway driving.

I just got a protective film installed on the windishield. I've had no experience with it before, so we'll see how it holds up.

Hi olanmills - what kind of film did you get installed on the windshield?

We should suggest that Mythbusters perform some high speed rock testing on the Model S windshield and compare the results to a few other cars in a controlled lab setting. To make it interesting, use an electric rail gun to propel the rocks.

I got ClearPlex. It's not perfectly invisible. The color is (or seems) perfectly transparent, but light does not come through perfectly smoothly. When looking at a straight edge through the windshield, the edge looks slightly wavy or pixelated (lol). It doesn't really bother me though. I think it's still worth it. On my old car, which I had to replace the windshield after a couple years after getting a large crack when the windshield was hit by a random, largish rock, but even disregarding that, with all of the highway driving I do, even after just three years, lots of tiny chips actually affected visibility when the sunlight hit at certain angles.

Chipped windshields will crack or even break completely if not taken care of as soon as possible after impact. Those impact marks will make water penetrate the laminated glass when the car is hot and tempered and if you shut down car in freezing weather - well you know frozen water will expand....

Go to a specialist and have them apply a clever "invisible" filling. I know my insurance company covers those jobs without me paying a dime - cause it is cheaper for the insurance company to pay for that little job then for a brand new windshield. So check with your insurance company - you might be surprised.

Thanks Olanmills and everyone.

I was looking at ClearPlex and I do a lot of highway driving too. I agree about the tiny chips over the years.

If you don't mind, what did the ClearPlex cost? My installer is looking into it.

thanks again!

It was $450 (including installation), which I believe might be on the high side. I don't really know because I didn't shop around.
