What is optimum gray? The permatex ultra grey/black sealers work very well to stop any type of seeping or leaks in coolant or oil applications. If its spread thin over the whole gasket surface & not just a small bead and allowed to fully cure, it literally seals the gasket & should stop any leaks or seepage. Unless there is major pitting that the sealer isnt filling, but even then on pitted timing covers if you fill the pits with the sealer it has always been leak free in my experiences.
