## Description

BlueDevil Rear Main Sealer is a product designed to fix leaks in the rear main seal of an engine. The rear main seal is a critical component of an engine, as it helps to keep the oil inside the engine and prevent it from leaking out. Over time, the seal can become worn or damaged, leading to leaks. Bluedevil Rear Main Sealer is formulated to be a non-particulate sealant that can mix with the engine oil and flow into the damaged areas of the rear main seal, creating a permanent seal. It is designed to work with all types of engine oil and can be used in both gasoline and diesel engines.
