What Houston heat is really doing to your paint
Texas sun, humidity and surprise hail are the three biggest enemies of a car's clear coat. Here's what we see in the shop — and what actually helps.
Every spring we get a wave of cars that look like they aged five years over the summer. Faded paint, hazy headlights, sticky dashboards. It's not the owner's fault — it's just what 95-degree humidity, 110-degree direct sun and a sudden Galveston rainstorm do to automotive finishes that aren't protected.
Clear coat fails from the top down. UV breaks the resin bonds, water spots etch into the softened surface, and the next round of sun cooks the etching into permanent damage. A ceramic coating is essentially a sacrificial layer that takes the UV hit so your clear coat doesn't have to.
Practical advice from someone who's seen a lot of Houston paint: park in the shade when you can, never let bird droppings or bug guts sit more than a day in summer, and rinse the car after pollen season even if you're not going to wash it. Those three habits alone add years to a paint job.
