Prep Wash is a waterless, inorganic surface cleanser formulated to remove contaminants and expose paint defects prior to correction and coating application. Free of oils and silicone, it leaves the surface in a chemically clean state that allows coatings to bond properly—making it particularly well-suited for vintage and restored vehicles where moisture must be avoided.

프렙 워시는 도막 교정 및 코팅 시공 전 오염물을 제거하고 도막 결함을 드러내기 위한 무수성 무기질 표면 세정제입니다. 오일과 실리콘이 전혀 포함되지 않아 코팅의 완전한 결합을 보장하는 깨끗한 표면 상태를 유지시켜 주며, 수분 노출을 피해야 하는 클래식카와 복원 차량에 특히 적합합니다.
