Can Auto Glass Be Buffed? A Comprehensive Guide

When you have a scratch on your windshield, it's usually necessary to buff or polish it in order to remove the blemish. A metal compound is used to buff or polish the scratch. Minor scratches on the windshield can usually be repaired with relative ease. These are the ones that are visible to the naked eye and when you run your nail through them, the nail doesn't catch on.

Since these scratches aren't deep, there are some simple ways to fix them. If you use cerium oxide, fill in the scratch and start buffing it gently. A drill and a rubber polishing wheel make buffing much easier. Continue to fill in the scratch with more cerium oxide and buff until the result is a clear, smooth repair.

For optimal results, apply cerium oxide to a cloth and then to the scratch. If the solution comes into contact with the glass, it may cause small scratches. Before repairing the scratch, make sure that there are no residues that could interfere with the bond between the repair product and the glass. If you have more serious scratches or these products don't work, you'll likely need to have your vehicle's glass repaired by a professional.
