Things You'll Need:
- Glass rubbing compound
- Variable speed drill
- Buffing pads
- Rags
- Glass Renew
-
Step 1
Perform a test to see if you can catch your fingernail on the scratch. If you can, the scratch is too deep and is not repairable. If your nail doesn’t catch, you can buff it out with a glass compound and a variable speed drill.
-
Step 2
Clean the windshield thoroughly. Make sure there’s no dirt, oil or debris on the area needing repairs.
-
Step 3
Use a glass rubbing compound. It typically comes in a glass repair kit, which you can purchase online or at your local automotive shop.
-
Step 4
Position a buffing pad on a variable speed drill and apply a small amount of the glass compound on the pad. Start by applying soft pressure for a few minutes, and work the compound in on the scratched surface in small circular motions. Keep the area of the windshield you’re working on wet at all times.
-
Step 5
Clean the area with a clean, wool rag. Apply a small amount of glass polish like Glass Renew on a clean buffing pad and position the pad in place on the drill. Work the polish onto the scratch using soft to moderate pressure. Continue working until the scratch is gone.
