Inland heat & freeway miles
What Pomona Valley roads do to cars.
Hot inland summers that oxidize clearcoat on roofs, hoods and trunks.
Sideswipes and rear-enders along the CA-57, CA-60 and I-10 corridors.
Rock chips from trucks serving the region's warehouses.
The I-10, CA-60, CA-57, CA-71 and I-210 all pass through, and the stretch where the CA-57 and CA-60 share lanes in Diamond Bar is one of the most congested truck corridors in the region.
Inland summers are hot and dry, and long freeway commutes add rock chips and debris strikes. Sun-damaged clearcoat and chipped front ends are the most common cosmetic problems we see from inland drivers.
