Key features

  • Formulated specifically to restore the original finish of undercarriage parts and shield them from road grime, dirt, and UV exposure.
  • Reaches wheel wells, subframes, suspension components, and fender liners — areas that are difficult to access with conventional products.
  • Oil-based formula bonds to surfaces and provides a durable coating that helps resist rust and corrosion over time.

Usage

  1. Clean the target area thoroughly to remove loose dirt and grease before application.
  2. Spray the product evenly onto the undercarriage surface from an appropriate distance, or apply via an applicator pad for more control.
  3. Allow to dry and wipe away any overspray to achieve a uniform satin-finish appearance.

핵심 특징

  • 언더캐리지 부품의 원래 마감을 복원하고 도로 오염물·UV로부터 보호합니다.
  • 일반 제품으로 접근하기 어려운 휠웰·서브프레임·서스펜션·펜더 라이너까지 커버합니다.
  • 오일 기반 포뮬러가 표면에 밀착해 녹·부식 억제 코팅을 형성합니다.

사용법

  1. 도포 전 대상 부위의 오염물과 유분을 깨끗이 제거합니다.
  2. 적정 거리를 유지하며 언더캐리지 표면에 고르게 분사하거나, 어플리케이터 패드를 이용해 정밀하게 도포합니다.
  3. 건조 후 과잉 분사된 부분을 닦아내 균일한 새틴 마감을 완성합니다.
