Adam’s Undercarriage Spray is designed for use on fender wells and wheel wells to leave behind a satin black finish. This product can also be used on trim, tires, and any undercarriage component. It helps to repel dust, dirt, and unwanted moisture from rust-prone areas. The spray lays a thin layer of dressing on the surface and can be layered for higher gloss. It is perfect for completing your comprehensive detail and will set your work apart from the rest. This quick and easy, sprayable solution makes restoring the deep, rich shine back to your undercarriage a breeze. It is also a great dressing for your engine compartment, making plastic and rubber look new again, shining painted surfaces, and keeping aluminum and anodized parts from corroding.
