Well none I have seen work without some superglue. It's hard to keep the eye clean and stick it in the right spot also. I don't do a lot of glue on eyes even though I have thousands, I use Loctite brush on superglue and I cut the brush down just a little. All I want is a tiny drop (really not a drop, but a bit) where the eye goes.
Now depending on the type of clear coat your wanting to use, some like Sally Henson's Hard as Nails will change the color of Chartreuse and FL Yellow so you don't want to use that over these two colors. Usually if I am going to clear coat I use Clear Vinyl. Actually if one is using clear vinyl as their clear coat I would think that would be enough to hold the eye in place ones it dries.
Like I said though, I don't do many glue on eyes so I feel sure someone on here knows better than I do!
