I use to superglue but hated it. I now bake mine on for 20 minutes at 220 and then head gets a coat of UV seal coat. No eyes have popped off and no mess. Some eyes I have found don't want to stay on that well while baking and believe this is limited to the adhesive baking on the eyes. I also have one batch of silver eyes I bought that want to get discolored when leaving in the full 20 minutes. When using these eyes I reduce the bake time. Really liking the UV seal coat as it seals any gaps you might have between the eye and head as well as gives the head a nice shine. Also protects the paint from chipping.
