How do I remove scratches in an automobile windshield?

Question

This is a 1995 Nissan Sentra. The scratches have been caused by the windshield wipers. Apparently the previous owner neglected to change the blades periodically.

Answer 1

I have some personal experience with this. The rubbing compound method won't work unless the scratches are VERY light, and even then you have to be careful, as too much rubbing wit h the abrasive rubbing compound will leave a hazy area on the glass (micro-scratches from the abrasives). You can go to your local auto glass shop and see if they can repair the wiper scratches, but even if they can (somewhat doubtful unless they're REALLY deep), the resin they use is not totally clear; you'll always be able to see the repair, even though it might make it look better short term. That kind of repair usually only works well on chips and stars.

Frankly, I'd eventually go with replacing it, because I honestly don't think you'll like the results otherwise. If it should get any further damage or develop a crack as a result of the scoring from the wiper scratches, your insurance will cover replacing it under "comprehensive" coverage. If you don't have that coverage, and can't afford a new windshield out of pocket, you can go to a salvage yard and obtain a good quality used one. Most auto glass places will install the used one for you for a modest fee (grudgingly, as they'd rather sell you a new one). Hope this info helped.

Answer 2

Depending on the depth of the scratches. You could either buff them out with rubbing compound or wax.

Of you will have to use a epoxy to fill in if they are deep. I would suggest you hire someone that is trained in doing this if you are not familiar with the technique. You can make the windshield worse or cause it to need replacement.
