Sealant

Originally a clear silicon sealant was used in all the joint to joint connections on most exhaust systems. This was referred to as "grease" in the assembly manual but it was a clear sealant like the one pictured here. After analyzing original samples off our pipes and searching incessantly we came up with a match with the seaman pictured here. This sealant comes as part of any Gardner Exhaust Kit
