Dow Corning makes an excellent product called  3145 RTV.  I believe GE 
also makes a similar product.  It comes in clear or grey and is 
non-corrosive.  There is also a primer that can be used with it to 
enhance it's "stickability."

Several years ago, I had oil seepage in an old car that would have 
required the removal of the head which I had neither the time or 
inclination to do.  I used 3145 RTV with primer and solved the leak.  It 
can be used for more than electrical work! :)
