Aggressive machine compound created for restoring badly oxidised gelcoats and weathered boat paint. The silicone-oil-free formula generates little dust or sling, making it suitable as a starting cut for severely chalked marine surfaces.

산화가 심하게 진행된 젤코트와 풍화된 보트 도장 복원을 목적으로 한 강력한 머신 컴파운드입니다. 실리콘 오일이 들어가지 않고 분진과 튐이 적어, 백화가 심한 마린 표면의 초기 절삭 단계에 활용됩니다.

Usage

  1. Place about five pea-sized drops onto a Heavy Cut Pad, short Lambswool Pad, or Twisted Wool Pad.
  2. Spread the compound across the panel at low speed before fully engaging the machine.
  3. Work crosswise on a rotary capped at 1000 rpm or an eccentric set to its highest setting until the surface is leveled.

  5. Finish by sealing with Gelcoat Finish, Marine Protective Sealant, or Ceramic Boat Hull to close the open pores.

사용법

  1. 헤비 컷 패드, 짧은 램스울 패드, 또는 트위스티드 울 패드에 콩알 크기 다섯 방울 정도를 짭니다.
  2. 본격 작업 전에 낮은 회전수로 컴파운드를 패널 전체에 펴 발라 둡니다.
  3. 로터리는 1000 rpm 이내, 이센트릭은 최고 단계로 십자 방향 작업해 표면을 평탄화합니다.
  4. 폴리시 앤 실링 타올로 잔여물을 닦고, 짙은 색 젤코트에서는 젤코트 마이크로 컷으로 자국을 다듬습니다.
  5. 마무리로 젤코트 피니시, 마린 프로텍티브 실런트 또는 세라믹 보트 헐로 실링해 열린 기공을 막아 줍니다.
