The primary purpose of a sealant is to properly protect your vehicle from the elements. Sealants are designed to bond to your paint and provide roughly 3 to 6 months of protection. This is significantly longer protection than what a carnauba wax offers, which is typically 3 to 8 weeks. The barrier of protection that sealants provide help minimize contamination from embedding in to your paint and makes maintaining your vehicle significantly easier. Another newer range of products are spray coatings.
