Parking is the thing that makes the Heights different. A lot of the older bungalow streets have no driveway to speak of, and the newer townhome developments in Shady Acres have narrow shared drives. We work in the space that is actually there rather than needing a two-car pad, and we will not block your neighbours in while we do it.
Cars here live outdoors and under mature trees, so they take sap, pollen and droppings continuously rather than seasonally. On a car that sits on the street full time, the difference a detail makes is more obvious than anywhere else we work, and it also stops holding as quickly.
Inner loop driving is stop-start, which means brake dust. Being close to 610 and I-10 makes it worse: that traffic throws off hot metal particles that bond into the clear coat and show up as tiny rust-colored specks that will not wash off.
The Heights is rebuilt street by street, and it has been for years. There is usually a teardown or a framing job somewhere on the block, which means concrete dust, sawdust and paint overspray settling on whatever is parked nearby. Overspray in particular sits proud of the clear coat and has to be levelled off rather than washed away.
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.
