What glues is best for stainless steel?

I am going to glue some synthetic leather (vynahide) to a piece of stainless steel. What type of adhesive should I use? Preferably water proof.
Sorry I can't go into details, it's a project I'm working on for a contest.
Help much appreciated! :)

A rubber contact glue would be fine.
