I just did this a couple months ago and asked the same question, perhaps the thread will be in the archives.  Lots of answers, almost like asking for an oil recommendation.  

After carefully checking all the holes for any bulging, assuming you have a steel sump.  I used Permatex Ultra Black RTV between the sump and the gasket and Permatex Aviation (the gooey brown stuff) between the gasket and the block.  Drop free as of this writing.

This doesn't sound like a sealant problem...  It's made to be a gasket dressing.  How could it weaken a gasket, especially a stout one like a sump gasket?
