Ferguson fender aprons were designed and form fitted to your C3 Corvette. The main feature of the fender apron is the premium exclusive material that has an outside black vinyl cover with sandwiched close cell foam and soft Nylon Tricot to protect the surface of your car. The Nylon Tricot material still allows air under the surface to let your paint breath while the fender apron is in place. This is an excellent cover for repair and mechanical shops and also works well on the judging field. The aprons have multiple attaching points that keep the apron in place while doing heavy mechanicals, normal maintenance, or on the judging field.
