For this bait, I think you will want to go with adhesive. Unless you are just using for yourself. Dipping will alter the look a bit but I doubt the action much, if any.
In my experience, as long as you coat the inside of the eye cavity good with loctite or super glue GEL version (and others I am sure), the eye will stick and hold up.
If you are using M-F plastic, the eye cannot touch the plastic anywhere or it will end up a gooey mess. I have not tested CCM long enough but so far, the eyes just get a little gooey if put directly on the plastic.
Swirl the glue well on the sides and bottom of the eye socket, stick in your eye and you will be good to go.
