E-Tech , there is a complete Kit at eneos 1 Utama called Glassy Lights , it contains everything you will need to Restore your Headlights to New in one easy Kit , It may be an Idea to get this , Or else you could use Sand Paper , But make sure the Grit is correct and replace Autosol with Meguires Plastx , This is designed to restore and protect headlights , then Wax and Buff and it should be fine
