I agree with that one. I caught hell recently for my C8 leaking on our driveway!

Most of my leaking problems come from the oil pan edge, despite proper gaskets and Permatex and correct torquing. I have running in oil in at the moment but when it comes time to change it, I may experiment with just silicone sealer - although not Permatex which I've found to be disappointing. Permatex Copper Seal head gasket aerosol sealer is worse than useless and I won't be using that again either !
I have had great success with these two products. I really cannot recommend them more highly, I've thrown out all my others rtv’s & only use this now, it’s that good. It comes in Grey too. The only difference is the dry time to put into service again.
