Brand is up to you. But typicially you get what you pay for.A paint sealant is made of polymers, which are composed of tens of thousands of synthetic particles that are linked together. When a sealant bonds to your vehicle’s paint, it forms a rigid shell. It is not the warm carnauba that seems to melt into the paint. Paint sealants sit on top of the paint like a transparent chain metal suit. They are glossy and slick, but carnauba lovers will tell you they do not have the warmth and depth of a carnauba. However, the real selling point of a paint sealant is the durability. A premium paint sealant can last upto 8 months, sometimes longer.
