Here are a couple of edited (to help show the damage) photos of the current, 15 year old factory lights. The driver's side is actually worse than the pictured passenger side.
Here's one with the hood open where you can see a half/half:
Here's the new ones with two good coats of Keep Clear:
One tip I'd suggest would be to have a can of compressed air on hand to blow the lens off well after wiping it down. I cleaned the first lens and then quickly blew on it, but there was still some a couple of contaminants on the lens that were coated over. I spent a little extra time on the next to avoid the issue. All the dust on the lens in these pictures is on the surface after it had dried already. The coating is still tacky on the rubber trim piece, but hopefully it'll help out as the trim on the aftermarket lights tends to fail sooner than later.
I'm happy with the product thus far!
