The beautiful thing about using the
EZ4u2 headlight restoration is you DO NOT have to remove the headlights from your car. In some cars removing can be easy but a lot of cars it just to much work. Plus in replacing the headlight you may have to refocus the beam. Why bother with that hassle. It's just a waste of time. The other thing is it depends on the type of oxidation warm water and 800 sand paper may work. But the headlights that has the peeling or rough oxidation that 800 will not even scratch the service. You may have to go down to a 400 grit or maybe a 220 grit sand paper and that is included in the kit.
This kit covers all types of oxidized headlights. It works for yellow headlights, the whitish hazy headlights, peeling headlight lens and as well as the rough scratchy ugly headlights. Here is a link to the instruction video for the EZ4U2 headlight restoration kit

What I like about this headlight restoration kit is you DO NOT have to remove your headlights from your car to restore your headlights and they come out looking like new. Plus they Guarantee it. That works for me.
