The tree cover here is the whole appeal and it is also the problem. The Woodlands was built around its pines, and a car parked under them collects sap, pollen and bird droppings faster than the same car three miles up the freeway. Sap in particular hardens onto the clear coat and stops being a wipe-off job within days, which is why cars in the villages tend to need attention more often than their owners expect.
It is a commuter corridor. Cars run I-45 south into the city and sit in a lot all day, so they pick up the highway contamination on the way in and bake it on while parked. Twice a year that includes lovebug season, and lovebug residue is acidic enough to etch paint permanently if it sits in direct sun.
Most homes here have a driveway and a garage, which makes this straightforward for us. We can work at the house while you are out, and the car goes back in the garage clean rather than sitting in a lot waiting for you to collect it.
The other half of the day happens in a parking lot. Town Center and the office parks along the corridor are mostly open surface parking, so the cars that leave a shaded garage in the morning spend the working day in full sun. Heat is what turns a contaminant sitting on the surface into one bonded to it, and that is the difference between a wash fixing it and not.
Contamination that has bonded into the clear coat needs decontamination rather than another wash. Paint correction removes it, and a ceramic coating is what stops it bonding again.
