Anyone ever used this on pre-98 headlights?

It's not available pre-cut. You have to buy bulk and do your own cutting. Wondering if it's a big PITA.

My idea is to give my headlights a good sanding/polish and then put some of this on to protect them.

I've read about clearcoating and such, but I'm wondering about this idea as an alternative.

TIA
