There are these marks on the car window that I can't get out. It has the words "CPR" and "4188" on the window. It also has a streak on it. When I rub my hand over the surface I can fill a bump. Any ideas of what could have caused it? I can't see it when it is dry, but once I put water on it it lights up like crazy. WTH!? Did some one spray clearcoat or use something hard to imprint it. I doesn't feel like it has been scratched but I feel a bump on it. It is like it is bruised. Any ideas of what it could be? Do you think I should go to my insurance company and get it fixed? 500 dollar deductible. =(.

 

Wow - maybe some writing from the factory that didn't get cleaned off properly. Start with Windex then more stronger cleaners like rubbing alcohol then acetone. If that doesn't do it then try some abrasive glass polish.

 

I thought it looked like factory markings as well. I tried acetone and alcohol and it's still there. =(

 

take it to the dealer, if its something from the factory, than its their fault

 

Xylene is next, maybe a sharp razor blade on a hot day then go for the abrasive polish and a buffing wheel - use lots of water afterwards and don't get it on the wiper blades.

 

Definitely not vandalism. See, here's the thing about vandals: they are not smart enough to use a clever technique like this, and their handwriting always sucks. This one has nice writing and a professional technique. Could you imagine a couple of vandals doing this? They like instant gratification. "Damn homie, this fool will be trippin when he washes his windshield 3 weeks from now." On top of that, these markings are meaningless. If it was vandalism then you would have a big ***** on your windshield or something.

 

Use Toluene... I had the same thing happen to mine... Just don't get it on the paint, it will take your paint right off.

 

I'm going to call the dealer tomorrow and see if they have anything to do with it. Even if they did, I'm sure they'll deny it. =(. My dad was trying to buff it out with some "quick-n-brite" lol. If all else fails, I'll try those products.

 

hey that looks like the writing they put on panes of glass to store and classify before install.
but it also looks like the price tags used car dealerships put on their car's window when they leave them outside in the sun.

 

same post. look down.

 

 

Use gloves also with Toluene and MEK......and do it outdoors.......it goes right to your liver........used to use a lot of it to clean parts making jets till they discovered it kills you.....

 

Where can I buy toluene? I'll dress up like an astronaut for protection. Where would I dispose of this stuff?

 

The first thing I would try would be a simple razor blade.

 

try Goo Gone!

 

those are dealer/factory marks. its like a window crayon/chalk. i had it for a while till i washed my car well.

 

After seeing this and reading---I find myself humming the Twilight Zone theme.............

 

Uh-oh, sounds like the work of Nicolas Cage. Don't let your tC out of your sight, or it might end up gone in 60 seconds.

 

I haven't watch that movie in a long time. No, I don't use a blacklight. Just a regular bulb.

 

Carb cleaner would be one possibility or some gas additive that contained the right stuff may take it off and you can put the rest in the fuel tank.
