OIL HOUSE TIP: Because the Black RS-660 has such a high temperature rating (up to 626°F), it is incredibly versatile. However, always ensure the surface is 100% free of old oil and residue using a parts cleaner before application. This ensures the silicone “bites” into the metal for a leak-free finish that lasts for years.
