Glass problem?

[stewarta13wsb]

I've used NXT window cleaner 2 or 3 times now but can't shift what I take to be the sucker marks from where the windscreen was fitted to my new car

You don't really see it unless the window steams up and it's on the inside of the front screen and tailgate, where it's harder to get any good pressure into the buffing, any suggestions appreciated

Here is a good glass cleaning post:

Is this on the inside or outside?

They're on the inside.

Hi Stewart,

Some vehicles have a winshield with a special coating on the inside of the windshield. Often in the owner's manual, they warn about the use of suction cups for radar detectors etc as they may permantly etch the glass.

If that is the case, no company's glass cleaner will remove this etching. I would suggest going back to the place that installed the windshield. I would advise against getting more aggressive with the windshield until you find out whether yours has this coating or not.

Thanks Tim, it's actually a new car (so no replacement) it came from the factory like this I guess

If it's on the inside of the front windscreen, I'd use some clay and QD as lube. Spray it on the claybar (while you are still outside!), go in and use the wet side of the clay on the mark. If it starts to get grabby, stop, wet the clay and repeat again.

As I mentioned above, doing anything further to the interior glass before checking with the manufacturer to see if this windshield has a coating or not, may create further, unrepairable damage.

The front windscreen of your car uses laminated glass, which is flexible transparent polymer sandwiched by 2 layers of glass. So the inside surface should be glass, the same as the outside. I am assuming that the guy did not tint his front windscreen (which is illegal over here).

Around 1994, certain car manufacturers (not all) began using a special film on the inside surface of the windshield. This coating was easily damaged from suction cups from radar detectors etc that would permently etch the coating. Yes, windshields do have an anti-break coating, sandwiched in the glass, that prevents the windshield from shattering in case of an impact. That is not the coating I am referring to. In all cases, before becoming too aggressive with the glass, it is prudent to check the owners manual to see if your vehicle has this coating.
