Protect the Underside of Your Vehicle from the Elements Bondo® Rubberized Undercoating helps protect the undercarriage of cars, trucks, vans and recreational vehicles from both corrosion and abrasion. The coating may also be used to protect wheel wells, quarter panels, interior sides of fenders, the underside of the hood, the bottom sides of floor pans and more. The rubberized undercoating also helps deaden noise, allowing for a more pleasant and quieter ride. The spray goes on as a textured black finish that resists chipping, abrasion, exterior rusting, and weathering. It provides one-coat build-up with no dripping, running, or sagging. Protecting your vehicle with an application of rubberized undercoating is advised for long-term protection of the undercarriage. Rubberized undercoating creates a protective barrier that seals out grit, grime and moisture that could otherwise corrode the metal components. This extra protection is a low-cost measure that can pay off by potentially extending the service life of a vehicle. Enjoy a More Pleasant Ride For a quieter ride, rubberized undercoating helps insulate the vehicle cabin from noise, including from the road and the engine. When soundproofing an automobile, consider the most common source of the noise for your situation. Cars of all makes, models and price ranges will benefit from noise reduction soundproofing.  Additional Uses This undercoat spray also has numerous applications for do-it-yourself improvements. It may be used to coat the section of fence posts buried underground to reduce decay. The spray is also effective when applied to roofs, gutters and downspouts to patch and seal leaks. Undercoating may be applied to gutters to stop leaks and to outdoor PVC pipes to cover the white coloring and provide more insulation. Exceptional Convenience The aerosol can offers exceptional convenience for applying the undercoating without any additional investment in equipment.
