What sealant to use to seal the headlamp back?
For our kit it doesn’t come with any sealant. In our installation procedure, the heating of the headlight will soften the existing sealants that are already on the headlight housings. When it cools down those existing sealants will stick back the housings. But if customers are not confident in using the existing headlight sealant, they can easily purchase a “silicone RTV sealant” which is available at any hardware store and spread it along the line of the headlight housings.
