Scratched Windshield Repair

NYC is the worst place to winterize your bike. Bike storage places and garages are too fracking expensive! Luckily I was introduced to a guy that rents a two car garage for his SUV and bike. He lets me store my bike there during the winter for only $50/month. Last month him or someone helping him move some stuff around put a long scratch across the top of my $180 windshield. Since I am only paying $50/month I wasn't sure what to do. I decided to try and repair the windshield and if that didn't work, then I would talk to him about it. Tonight I repaired it. It looks better than it did new! Process and photos below.

The scratch



I used wet/dry sandpaper and Novus Plastic Polish. I started by testing which grit I needed to start with. On the deepest area of the scratch, I dry sanded starting high (7000) and worked my way down (800) until I found which grit I needed to start with. If you start with too high of a grit, then you will never get rid of the scratch. If you start with too low of a grit, then you add more work for yourself. Once you have decided which grit to start with, wet sand the entire scratch. Wet sanding prevents the sandpaper from clogging with plastic dust. All you need is a cereal bowl filled with water. Dip your sandpaper in to the water and then start sanding. When your slurry starts to get white with plastic dust, dip your sandpaper back in the bowl to wash it off and to carry more water to your windshield.

I started with 800 grit



I then worked my way up through 1000, 1200, 1500, and 2000 grit. I sanded with each grit in a circular motion and then finish with straight up and down strokes. That way, when I moved to the next higher grit I knew I was done and ready to move on the next grit when all the straight sanding marks where gone.




I then sanded with 3000 grit. After that I moved to the Novus Plastic Polish. I started with #3, then #2 and finished with #1. I simply followed the directions on the box.

GOOD AS NEW!!!

Thanks. I was very skeptical about being able to get rid of sanding marks and cloudiness. I was really surprised at how crystal clear the windshield was after the polish.

Yeah, that Novus stuff rocks. I have a small bottle of the super fine polish that I use just to clean up visors and windscreens when Plexus won't do.
Thread be stuck.

Ineresting. I've never used anything but hot water on mine to avoide scratching and cloudy. I'd love to see someone with a cloudy screen try this and see if it restores it.
