Ahhhhh "The Wrong Stuff" I have seen Many oil pans leak with this stuff and it is Very hard to get off once it is on and a complete mess to clean up.... The last one we repaired was at this years TB.com event at Richard Clarks place.... What a mess!
Oil pans were meant to have gaskets and I personally like the cork gaskets where I have seen the blue silicone ones also squeeze out and leak....The dimples pressed into the rim of the oil pan where the gasket goes are supposed to be like a "stop" to help prevent the pan from squishing gaskets but I have seen it happen... I have a cork gasket on mine and there is absolutely no leaks under my car what so ever!
