Use of RTV with 1 piece oil pan gasket?? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

This is an old question which keep coming back - do you use RTV or any other gasket sealer with 1 piece oil pan gasket such as Fel Pro 1880K? I just pulled an oil pan of a recently built 350 which was put on dry except for the half moon corners. It leaked at the bottom of the front lip, while the rest of the gasket perimeter was dry like a rock. Which begs the question - should RTV be used and where??? Does any one know? Fel Pro installation sheet that comes with gasket is rather useless in this regard. Oil pan appears to be flat and square.

Thanks
