Underbody Protection
Underbody protection is the coating and panels that protect the bottom of the car from stones, water and salt.
What is Underbody Protection?
It includes PVC coatings, wax and plastic panels. Panels also improve aerodynamics and reduce noise. Damaged panels can hang down and catch. Many cars have a plastic engine undertray that also guides cooling air; driving without it can affect cooling and let water reach belts and electrics.
How it works
Coatings seal the metal; panels deflect stones and water.
Why it matters for your car
Check the underbody after off-road or deep water. Loose panels can damage other parts.
