Hi Lucia,

The headlight kit will work for sure. Just make sure:

Tape off the surrounding areas of painted bodywork
you use only the sandpapers in the kit
keep the paper and headlight lens very wet as you sand
Don't push hard, just let the paper do the work

When you get to the end of the process, clean off all residue and let the lens dry. Inspect closely and look for inconsistencies in the result. If present, redo the process until satisfied.

Should you get to the end and feel the optical clarity could still be a bit better, then use some compound followed by polish for a perfect result. The compound and polish can be applied with foam hand applicators or a DA buffer.

If the kit you have includes a clear coat as the very last stage, only apply it once you are completely happy with your the results of your sanding and polishing.

Good luck!
