My headlights look like I just went mudding, all the time.

I took my headlights out to install some fog lights today.
Since I have them out I decided to sand and clear them.

We restore headlights at work (one of my many jobs).
We sand the headlights with 1000, 1500, 2000.
Then we use automotive two part clear.

I guess I'll find out how long this way will last.
