Rocker panel (sill)
The rocker panel, also called the sill, is the structural body section that runs along the bottom of the car between the front and rear wheels, just below the doors.
What it means
Rocker panels are part of the car's primary structural cage. They tie the front and rear of the body together, anchor the door hinges and door latches indirectly, and provide the jacking points for service work. They are also the panel most exposed to road grit, kerb scrapes, and water spray, and on cars driven in salt-rich environments they are the first place rust appears. In Singapore the corrosion concern is lower (no road salt), but kerb scrape damage is common. Cosmetic damage to rocker panels (scuffed paint, light dents) is straightforward respray work. Heavier damage that bends the rocker structurally is a much bigger job, since a bent rocker affects door alignment, ride height, and the geometry the car was designed around. Many cars have rocker covers (plastic side skirts) over the metal rocker panel, and these are easier to remove and replace than the underlying structural panel.
Why it matters in Singapore
Singapore's tight HDB carpark spaces and steep multi-storey carpark ramps are where most rocker-panel damage happens. Owners of low-slung cars (sports models, sedans with body kits) see rocker scrape damage frequently. Repair scope depends on whether the damage is to a removable plastic cover or the metal panel underneath, which a proper inspection determines.
How Revol Carz handles this
Revol Carz scopes rocker damage in person and quotes accordingly: plastic cover replacement is a fast turnaround, metal-panel work is a longer respray or structural job depending on the damage.
