Rock

[mbeach]

I rarely go a week without picking up a rock chip in my windshield. My wife's ML55 has no less than 8 in there right now, counting the two that I got this weekend.

It's not the end of the world, but it is annoying. If the chips are within a few inches of a corner, they might lead to cracks sooner. If the chips have a "star" shape to them, they will definately crack eventually.
If you're worried, put some clear nailpolish on the inside and outside of the chip -this will slow its spreading.

If it's a true rock chip (rounded edges, small hole), than a decent glass shop can repair it without a problem. If it's a "star", (with straight lines), then there's nothing that they can do without making it worse.

Forget about it ever being perfect, if it really bothers you, you might want call around for new glass now (exact replacement).

My insurance company offers $50 glass deductable -maybe yours does too?
There's so much gravel on the roads up here, that most glass shops will do a replacement for whatever the insurance pays out.
I generally get a new windshield every year.

I was always surprised with the VX's windshields. I had a truck in Canada fling a big stone at the windshield and it bounced off without a problem. The MB (and now my Dmax) will chip a window if you look at them funny.

I just called my insurance company and they are sending someone out to repair it. Its just a small chip now, so I hope they can fill it or whatever and prevent it from spreading. Its free and does not affect my premium, so hopefully it won't make matters worse.

Reno is bad too, I am constantly hearing rocks hit my windshield.

My insurance said I will pay a $500 deductible to have them replace the glass if that is the route I need to take, so I opted for the repair first.

i havent had any chips in the VX windshield knock on wood.. but I keep this stuff called E-6000 in my toolbox.. ive used it on a few rock chips in windshields, just filled it into the chip, press it in with a razor blade and let it cure for a day or two then scrape the excess off with a razor.. i havent had any chips spread after doing this.. i get it at acmoore.. but i dont think they have those out your way.. so maybe a craft store of some kind.. its a silver tube

Well, since its free and does not affect my insurance, I am having them come out and fix it this afternoon.

I'll report back with the results.

I had great luck with window repair for a crack (maybe a 1/2 inch wide). WIth a recommendation, I took it to someone and had it fused. You could still see the crack but it never grew.

The kits I've used in the past are a UV cure epoxy. The kit comes with a tube, plunger & adhesive disk. Put the adhesive disk over the chip & attach the tube. Then pull the plunger to create a vacuum in the cracks, release the plunger to allow the epoxy to fill the crack. Repeat the process a few times to make sure there is no air in left in the cracks (any remaining air will be visible after the epoxy cures). Let it sit in the sun for 40 minutes then remove the adhesive disk & clean. The only draw back is that it NEEDS to be a sunny day when you do it & probably above 50 degrees. I've had great luck with it & you should be able to pick it up at any parts store.

BTW - the professional treatment is basically the same - just fancier (electric pump to pull the vacuum & a UV light for curing).

Most insurance companies will now waive the deductable if the repair works since it is far cheaper for them than replacement (even with deductable). That's why you should take care of it sooner rather than later - everyone loses when it reaches the point of needing to be replaced. Remember that it's the thermal cycling that causes the cracks to spread (& pushing on it to see what happens) so this is the worst time of year to get one. If you have one, fix it now.

Keep us informed on the repair. Curious to see if you get better professional results than I did.

I would not recommend the clear finger nail polish repair. I'm sure it will make the blemish look better but will do nothing to stop the cracks from spreading. The sealant needs to get down in the crack.

Never heard of E6000 so I can't say from experience if it works or not.

Shop around for the repair kit but don't buy it now. Wait till you need it. Most UV epoxy has a limited shelf life.
