I had a customer come by the house this morning for me to do a little cosmetic work on his M3. The wind deflector had gotten off alignment on the wiper arm and dragged across a section of the windshield leaving tons of scratches taking up about a 5"x12" area along the a-pillar. You can see in the pics, I have the damaged area marked off with tabs of painters tape so I know what area to focus in. Since the scratches werent too deep, I started with 500grit sand paper on a buffer to get the initial damage out of the windshield. After that, I went to 1000grit, then 2000grit. Then with some buffing compound/polish I hit that whole area of the windshield with a buffing pad. Took about 45mins including setup and breakdown of the drop clothes. But when it was all done, good as new. This is something that I do fairly often, so I figured Id share since scratches on windshields from wiper arms are pretty common. Only took a couple pics. Cant see too much in them, but here they are anyway
Just getting setup. Cover the car so I dont get dust and buffing compound/polish all over everything, You can see the damage area marked with tabs of painters tape
Damaged area after being hit with 500grit to get the scratches out of the laminate.
And a final view from the inside after I was done. Scratches are all gone. (I didnt get a before pic because Im an idiot)
