2004 foreman es shift shaft oil seal

Hi all. I need a bit of help here. My oil seal that goes on the emergency shifter shaft keeps coming out. I am gonna pick up a new seal for it. I think I want to put a bit of Loctite around the outer edge to hold it in there real good for peace of mind. Which Loctite product should I use for this. Appreciate any help. I was thinking Loctite 518??? Thanks
