How can I protect my car's paint in Denham Springs' humid climate?

Keep the paint clean of the things that etch it, and keep a sacrificial layer between the clear coat and the weather. In Livingston Parish the threats are constant humidity, afternoon rain that dries into mineral spots, months of direct sun, spring pollen and, along the Amite River and I-12, road film. Each one is minor on its own; together they dull a clear coat in a couple of summers.

Three levels of protection, in order of how long they last. A spray sealant, applied after a hand wash and clay bar in our wash, clay and seal (from $145), lasts about three months and is the right maintenance step between details. A paint sealant package extends that. A graphene ceramic coating (from $750) is rated for three years and makes the surface hydrophobic, so rain sheets off instead of drying into spots, pollen rinses away and UV has a hard layer to work through before it reaches the paint. Paint correction comes first when the clear coat already has swirls or water-spot etching, because a coating locks in whatever is under it.

Between services, rinse bird droppings and sap the day you see them, avoid brush washes, and dry the vehicle rather than letting well water evaporate on it. All of this is done at your Denham Springs address; our auto detailing in Denham Springs page lists the packages.
