Headlight polish kit

These 3M headlight restore kit part #39173 - work well. Pretty inexpensive, about $8 at the store, and $5-6 on Amazon. Just tape off paint around the headlight. Clean the headlight with isopropyl and water. Then using water and the grey sanding pad provided sand the headlight. when you are all done, the the whole headlight will be hazy looking. Then dry it off. And then afterwards use the towelette provided, wipe it on the headlight. it's a real light clearcoat for the headlight. I applied it, and put the towelette back in the pouch so it wouldn't dry out, and let it the headlight dry for about 20 minutes then reapplied the clearcoat again.
I felt it worked well for the little time and cost associated with it.
