  • Acrylic sealant: Acrylic sealants are the most commonly used sealants and are ideal for protecting headlight housings from scratching and other damage.
  • Silicone sealant: Silicone sealants are also effective and provide excellent protection against moisture and dirt.
  • Epoxy Sealants: Epoxy sealants are more durable than other sealants and are ideal for protecting headlight housings from extreme temperatures.
