Consumer Reports listed Sylvania and 3M as the best with Sylvania edging out 3M. I had used 3M before and it worked well, I like the drill attachment.

So I tried Sylvania and it was quite a bit more work. It did have a good UV sealant that was difficult to spread evenly the length of the Headlight without re-applying, something they frown upon in the instructions.

It was a toss-up. I think I spend $100 next time and have a professional do it, because it WILL NEED a next time, unfortunately...
