@dpwperformance: How to, Headlight Restoration. I started with 180 grit wet sandpaper, all the way up to 2000 grit, and then used the ammonia pot that came in the kit. Turned out great for a first time doing it. A couple spots didn't come clear and I realized it's wear I touched some spots up with dry sanding. Make sure you keep it wet and always sanding the last grits scratches off. There was actually deep scratches from someone else that attempted restoring them. #headlightrestoration #headlightrepair #restoration #beforeandafter #educational #gmc #acadia #headlights #bigblock #smallblock #ls #dpwperformance
