Clear bra is a thick, nearly invisible urethane film (paint protection film, or PPF) applied over paint to absorb rock chips, road debris, bug etching, and light scratches before they reach the finish. Quality films self-heal minor swirls with heat and typically carry multi-year warranties against yellowing or peeling.
The classic package covers the impact zones: full front bumper, a partial or full hood, front fenders, mirror caps, and sometimes headlights and rocker panels. Full-body coverage exists for people protecting a special car.
Pricing scales with coverage and installer skill, from a partial-front package in the several-hundred-dollar range to four figures for full-front, and well beyond for full body. Installation quality matters as much as the film brand: edges, wraps, and alignment are where cheap jobs show.
No. PPF is a physical film that absorbs impacts; ceramic coating is a chemical layer that adds gloss and makes washing easier but stops zero rocks. Many enthusiasts do film on the front, coating everywhere.
Professionally installed and removed film on factory paint generally comes off clean. Removal from repainted panels carries more risk; tell your installer about any repaints.
Quality films are commonly warrantied for 5 to 10 years against defects like yellowing and cracking. The film still takes the hits meant for your paint, so expect it to accumulate battle scars; that is its job.
